Abstract

The journal of physical chemistry letters 11(7), 2497 - 2501 (2020). doi:10.1021/acs.jpclett.0c00158, Auger spectroscopy has previously been used to study changes in the hydrogen bond network in liquid water, but to the best of our knowledge it has not been used to track such changes as a function of temperature. We show Auger spectroscopy to reflect the weakening of the hydrogen bond network upon heating. This shows that the radiation response of water, i.e., the relative propensity of the different processes occurring after radiation exposure, including femtosecond proton dynamics, depends on the temperature of the system. This proof-of-principle study further demonstrates the suitability of the technique to help elucidate information on the intermolecular structure of liquids such as water, opening the door to further temperature-dependent studies., Published by ACS, Washington, DC

Abstract

Very recently, the Pierre Auger Collaboration reported a 4.5σ correlation between the arrival directions of the highest energy cosmic rays and nearby starburst galaxies. The cosmic rays producing the anisotropy signal have been proposed to originate in low-luminosity gamma-ray bursts (llGRBs). On the basis of the well-justified assumption that at redshift z 0.3 the host metallicity is a good indicator of the llGRB production rate, we show that the association of llGRBs and the starbursts correlating with Auger data is excluded at the 90% confidence level.

Abstract

Triple and quaternary solutions of materials of the A3B5 group, InGaAs arsenides and InGaAsP phosphides, are used in modern devices for the short-wave infrared range of the spectrum for various purposes. In this paper, we perform estimates and modeling of lifetime in А3В5 structures in accordance with the three fundamental generation-recombination mechanisms: radiative, Auger, and Shockley–Reed–Hall. Based on the estimates, lifetime in the In0.53Ga0.47As material of n-type conductivity in the concentration range of 1013–1017 cm–3 is 10–5 to 4.5 × 10–4 s, which allows high photoelectric parameters.

Abstract

Purpose. The research is devoted to the experimental choice of injection composition for auger technology of installation of underground anti-filtration shields under the source of pollution. The auger technology for the arrangement of an anti-filtration shield consists of pilot holes made by the horizontal directional drilling, which is followed by the arrangement of a waterproof layer by replacing the soil with auger by special concrete solution. Methodology. The main research method is experimental-statistical modeling, which includes conducting laboratory tests; correlation-regression analysis of the obtained data; qualitative, quantitative and graphical analysis of the obtained regularities of the studied indicators change from the varied factors. Findings. The main results of the study are the following: substantiation of the relevance of the development of the auger technology for the protection of underground space; development of methods and conducting laboratory experiments in choosing the injectable solution; analysis of experimental and statistical regularities of changes in water absorption and time of plastic strength setting when varying the composition of the anti-filtration shield (concentration of fiber, bentonite, water glass); development of the concept of technology of the anti-filtration shield arrangement. Originality. Experimental studies made it possible to establish that the minimum water absorption of the shied samples is observed at the lowest concentration of fiber (0.5%), bentonite (1%) and liquid glass (2%) in the injected solution. For structures of small width (1020m), there are suitable compositions with a minimum time of plastic strength setting at a concentration of fiber (3%), bentonite (5%) and water glass (18%). For structures with a large width (4060m), there are suitable compositions with a long time of plastic strength at a concentration of fiber (9%), bentonite (5%) and water glass (6%). Practical value. Experimental results made it possible to develop technological recommendations for construction of anti-filtration shields using the auger technology. Namely: to develop a concept and procedure of works, to calculate the costs of labor and machine time, to compile a list of necessary materials, machinery and equipment.

Abstract

We have previously developed CsPbBr3 NCs exhibiting a tremendously high photoluminescence (PL) and structural stability by adding ZnBr2. However, understanding of these outstanding properties is lacking due to the absence of spectroscopic analyses, such as spectral or dynamical characteristics. In this work, we conducted a comparative analysis of photophysical properties for conventional-CsPbBr3 NCs and ZnBr2–CsPbBr3 NCs. First, we analyzed the blinking traces by comparing the single crystal PL intermittency. It has been found that the PL quantum yield of CsPbBr3 NCs is gradually decreasing at the ensemble level, resulting from a significant activation of the Auger-induced blinking. Furthermore, the time-resolved TA dynamics supports the fact that Auger-type energy transfer accelerates the hot carrier cooling time, and thereby the Auger-induced blinking behavior in the band-edge state becomes dominant over time. Here, ZnBr2–CsPbBr3 NCs showed a low multiexciton Auger amplitude and therefore had a stable PL emission compared with conventional-CsPbBr3 NCs. Finally, we suggest that both NCs differ in intraband spacing possibly due to capping ligands, finally leading to a suppressed Auger process and higher stability for ZnBr2–CsPbBr3 NCs.

Abstract

Auger radiopharmaceutical therapy is a promising strategy for micrometastatic disease given high linear energy transfer and short range in tissues, potentially limiting normal tissue toxicities. We previously demonstrated anti-tumor efficacy of a small-molecule Auger electron emitter targeting the prostate-specific membrane antigen (PSMA), 2-[3-[1-carboxy-5-(4-[125I]iodo-benzoylamino)-pentyl]-ureido]-pentanedioic acid), or 125I-DCIBzL, in a mouse xenograft model. Here, we investigated the therapeutic efficacy, long-term toxicity, and biodistribution of 125I-DCIBzL in a micrometastatic model of prostate cancer (PC). Methods: To test the therapeutic efficacy of 125I-DCIBzL in micrometastatic PC, we used a murine model of human metastatic PC in which PSMA+ PC3-ML cells expressing firefly luciferase were injected intravenously in NSG mice to form micrometastatic deposits. One week later, 0, 0.37, 1.85, 3.7, 18.5, 37, or 111 MBq of 125I-DCIBzL was administered (intravenously). Metastatic tumor burden was assessed using bioluminescence imaging (BLI). Long-term toxicity was evaluated via serial weights and urinalysis of non-tumor-bearing mice over a 12-month period, as well as final necropsy. Results: In the micrometastatic PC model, activities of 18.5 MBq 125I-DCIBzL and above significantly delayed development of detectable metastatic disease by BLI and prolonged survival in mice. Gross metastases were detectable in control mice and those treated with 0.37-3.7 MBq 125I-DCIBzL at a median of 2 weeks post-treatment, versus 4 weeks for those treated with 18.5-111 MBq 125I-DCIBzL (P

Abstract

—The surface layers of polycrystalline tin are analyzed by Auger electron spectroscopy at temperatures of 293–473 K after being in contact with a nitrogen medium at different pressures and after 100–700-eV nitrogen-ion bombardment. It is established that after nitrogen-ion bombardment, a 389-eV peak appears in the Auger spectra, which is assigned to the nitrogen Auger transition KL2,3L2,3. The dependences of the surface nitrogen concentration on the sample temperature, the bombardment duration, and the energy of nitrogen ions are studied. It is noted that the appearance of nitrogen on the surface of Sn results in a shift of the Sn MNN peaks to lower energies, which indicates the formation of a Sn3N2 film. Argon-ion profiling of the sample surface shows that the thickness of the obtained tin-nitride film is one single layer. From the Auger-analysis data it follows that the film does not decompose up to the melting point of tin.

Abstract

This paper presents an investigation on the effects of micropillar physical parameters (height, pitch and diameter) on the optical and electrical performance of ZnO/ZnTe core-shell micropillar solar cells. It also studies the effect of the doping level in the absorber layer on the device’s performance considering the impact of Auger’s recombination. A Finite-Difference Time-Domain (FDTD) solver, Lumerical, is used for the numerical analysis. Based on the range of parameters analyzed it was concluded that for a core-shell ZnO/ZnTe micropillar solar cell a 4 $\mu \text{m}$ height, a 0.5 $\mu \text{m}$ pitch, a 70 nm ZnTe shell thickness and a $2.16 \times 10^{19}$ cm $^{-3}$ doping concentration for ZnTe achieves an efficiency of 17%.

Abstract

We discuss a fragment-based QM:QM scheme as a practical way to access the energetics of vertical electronic processes in the condensed phase. In the QM:QM scheme, we decompose the large molecular system into small fragments, which interact solely electrostatically. The energies of the fragments are calculated in a self-consistent field generated by the other fragments and the total energy of the system is calculated as a sum of the fragment energies. We show on two test cases (cytosine and a sodium cation) that the method allows one to accurately simulate the shift of vertical ionization energies (VIE) while going from the gas phase to the bulk. For both examples, the predicted solvent shifts and peak widths estimated at the DFT level agree well with the experimental observations. We argue that the QM:QM approach is more suitable than either an electrostatic embedding based QM/MM approach, a full quantum description at the DFT level with a generally used functional or a combination of both. We also discuss the potential scope of the applicability for other electronic processes such as Auger decay.

Abstract

We present measurements of the large-scale cosmic-ray anisotropies in right ascension, using data collected by the surface detector array of the Pierre Auger Observatory over more than 14 years. We determine the equatorial dipole component, ~d⊥, through a Fourier analysis in right ascension that includes weights for each event so as to account for the main detector-induced systematic effects. For the energies at which the trigger efficiency of the array is small, the “East-West” method is employed. Besides using the data from the array with detectors separated by 1500 m, we also include data from the smaller but denser sub-array of detectors with 750 m separation, which allows us to extend the analysis down to ∼ 0.03 EeV. The most significant equatorial dipole amplitude obtained is that in the cumulative bin above 8 EeV, d⊥ = 6.0 +1.0 −0.9%, which is inconsistent with isotropy at the 6σ level. In the bins below 8 EeV, we obtain 99% CL upper-bounds on d⊥ at the level of 1 to 3 percent. At energies below 1 EeV, even though the amplitudes are not significant, the phases determined in most of the bins are not far from the right ascension of the Galactic center, at αGC = −94◦ , suggesting a predominantly Galactic origin for anisotropies at these energies. The reconstructed dipole phases in the energy bins above 4 EeV point instead to right ascensions that are almost opposite to the Galactic center one, indicative of an extragalactic cosmic ray origin., La lista completa de autores puede verse en el archivo asociado., Instituto de Física La Plata

Abstract

Enhanced many-body interactions due to strong Coulomb interactions and quantum confinement are one of the most prominent features of two-dimensional systems. The Auger process is a representative many-body interaction typically observed in two-dimensional semiconductors, determining important physical properties of materials, such as carrier lifetime, photoconductivity, and emission quantum yield. Recently, platinum dichalcogenides, represented by PtSe2 and PtS2, have attracted great attention due to their superior air stability, thickness-dependent semimetal-to-semiconductor transition, and exotic magnetic characteristics. However, the Auger process in platinum dichalcogenides has not been investigated to date. Here, we utilized ultrafast optical-pump terahertz-probe spectroscopy to explore carrier dynamics in few-layer semiconducting PtSe2. Most of the excited carriers are trapped by defects within ∼10 ps after excitation due to high defect density. We overcome this challenge by raising the excitation intensity to saturate trap sites with carriers, and observed a many-body process involving the carriers that survived the rapid trapping. This process is not band-to-band Auger recombination, but rather defect-assisted Auger recombination in which free carriers interact with trapped carriers at defects. Theoretical simulations show that this three-body Auger process can be approximated as bimolecular recombination at the rate of ∼3.3 × 10−3 cm2 s−1. This work provides insights into the interplay between ultrafast many-body processes and defects in two-dimensional semiconductors.

Abstract

The Auger Engineering Radio Array (AERA) is currently the largest array of radio antennas for the detection of cosmic rays, spanning an area of $17$ km$^2$ with 153 radio antennas, measuring in the energy range from $10^{17.0}$ to $10^{19.0}$ eV. It detects the radio emission of extensive air showers produced by cosmic rays in the $30-80$ MHz band. The cosmic-ray mass composition is a crucial piece of information in determining the sources of cosmic rays and their acceleration mechanisms. The depth of the shower maximum, $X_{max}$, a probe for mass composition can be determined with a likelihood analysis that compares the measured radio-emission footprint on the ground to an ensemble of footprints from CORSIKA/CoREAS Monte-Carlo air shower simulations. These simulations are also used to determine the resolution of the method and to validate the reconstruction by identifying and correcting for systematic uncertainties. We will present the method for the reconstruction of the depth of the shower maximum, achieving a resolution of up to $15$ g/cm$^2$, show compatibility with the independent fluorescence detector reconstruction measured on an event-by-event basis, and show that the data taken over the past seven years with AERA shows a light cosmic-ray mass composition reconstruction in the energy range from $10^{17.5}$ to $10^{18.8}$ eV.

Abstract

A promising energy range to look for angular correlations between cosmic rays of extragalactic origin and their sources is at the highest energies, above a few tens of EeV (1 EeV ≡ 1018 eV). Despite the flux of these particles being extremely low, the area of ∼3000 km2 covered at the Pierre Auger Observatory, and the 17 yr data-taking period of the Phase 1 of its operations, have enabled us to measure the arrival directions of more than 2600 ultrahigh- energy cosmic rays above 32 EeV. We publish this data set, the largest available at such energies from an integrated exposure of 122,000 km2 sr yr, and search it for anisotropies over the 3.4π steradians covered with the Observatory. Evidence for a deviation in excess of isotropy at intermediate angular scales, with ∼15° Gaussian spread or ∼25° top-hat radius, is obtained at the 4σ significance level for cosmic-ray energies above ∼40 EeV., Argentina-Comision Nacional de Energia Atomica, ANPCyT, Consejo Nacional de Investigaciones Cientificas y Tecnicas (CONICET), Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP) 2019/10151-2 2010/07359-6 1999/05404-3, Ministry of Education, Youth & Sports - Czech Republic LTT18004 LM2015038 LM2018102 CZ.02.1.01/0.0/0.0/16_013/0001402 CZ.02.1.01/0.0/0.0/18_046/0016010 CZ.02.1.01/0.0/0.0/17_049/0008422, French National Research Agency (ANR) LABEX ANR-10-LABX-63 ANR-11-IDEX-0004-02, Consejo Nacional de Ciencia y Tecnologia (CONACyT) 167733, Netherlands Organization for Scientific Research (NWO) DIR/WK/2018/11, National Science Centre, Poland 2016/22/M/ST9/00198 2016/23/B/ST9/01635 2020/39/B/ST9/01398, Romania-Ministry of Research, Innovation and Digitization, CNCS/CCCDIUEFISCDI within PNCDI III PN19150201/16N/2019 PN1906010 TE128 PED289, Slovenian Research Agency - Slovenia P1-0031 P1-0385 I0-0033 N1-0111, Spanish Government FPA2017-85114-P PID2019-104676GB-C32, Xunta de Galicia, European Commission ED431C 2017/07, Junta de Andalucia Feder Funds SOMM17/6104/UGR P18-FR-4314, RENATA Red Nacional Tematica de Astroparticulas FPA2015-68783-REDT, Maria de Maeztu Unit of Excellence MDM-2016-0692, United States Department of Energy (DOE) DE-AC02-07CH11359 DE-FR02-04ER41300 DE-FG02-99ER41107 DE-SC0011689, National Science Foundation (NSF) 0450696, Gobierno de la Provincia de Mendoza, Municipalidad de Malargue, NDM Holdings and Valle Las Lenas, Australian Research Council, Belgium -Fonds de la Recherche Scientifique (FNRS), FWO, Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPQ), Fundacao de Apoio a Pesquisa do Distrito Federal (FAPDF), Financiadora de Inovacao e Pesquisa (Finep), Fundacao Carlos Chagas Filho de Amparo a Pesquisa do Estado do Rio De Janeiro (FAPERJ), Ministerio da Ciencia, Tecnologia, Inovacoes e Comunicacoes (MCTIC), France-Centre de Calcul IN2P3/CNRS, France-Centre de Calcul IN2P3/CNRS Centre National de la Recherche Scientifique (CNRS) Departement Sciences de l'Univers (SDU-INSU/CNRS), Federal Ministry of Education & Research (BMBF) German Research Foundation (DFG) Finanzministerium Baden-Wurttemberg Helmholtz Alliance for Astroparticle Physics (HAP) Helmholtz Association Ministerium fur Innovation, Wissenschaft und Forschung des Landes Nordrhein-Westfalen Ministerium fur Wissenschaft, Forschung und Kunst des Landes Baden-Wurttemberg, Italy-Istituto Nazionale di Fisica Nucleare (INFN), Istituto Nazionale Astrofisica (INAF), Ministry of Education, Universities and Research (MIUR), CETEMPS Center of Excellence, Ministry of Foreign Affairs and International Cooperation (Italy), Universidad Nacional Autonoma de Mexico, Programa de Apoyo a Proyectos de Investigacion e Innovacion Tecnologica (PAPIIT), Netherlands-Ministry of Education, Culture and Science Netherlands Organization for Scientific Research (NWO), SURF Cooperative, Portuguese Foundation for Science and Technology, FEDER funds within Programa Operacional Factores de Competitividade through Fundacao para a Ciencia e a Tecnologia (COMPETE), The Grainger Foundation x, Marie Curie-IRSES/EPLANET, European Particle Physics Latin American Network, UNESCO

Abstract

With the knowledge and statistical power of over a decade and a half of measurements, the Auger Collaboration has developed, assessed, and refined robust methods for reconstructing the energies and arrival directions of the highest-energy cosmic rays from the signal and timing measurements of its surface detector array. Concurrently, the unearthing of an increasingly complex astrophysical scenario and tensions with hadronic interaction models have demanded the addition of primary mass as an observable measurable using the surface detector. Access to information on the mass hinges on the disentanglement of the electromagnetic and muonic components of extensive air showers. Consequently, an upgrade to the Observatory, AugerPrime, is being carried out by equipping existing water-Cherenkov stations with a 3.8 m$^2$ Scintillator Surface Detector (SSD). The SSDs, with their high sensitivity to electrons and positrons, will provide samples of the lateral distribution of particles at the ground that complement those of the water-Cherenkov detectors, which are significantly more sensitive to muons. When used together, the two measurements enable extraction of the number of incident muons, which is a quantity that strongly correlates with primary mass. We describe the reconstruction methods being developed for application to measurements of the surface detector of the Observatory with a particular focus on the enhancement of these methods with data of the SSDs of AugerPrime. Results from the reconstruction of thousands of high-energy events already measured with deployed SSDs are also shown.

Abstract

The development of an extensive air shower depends not only on the nature of the primary ultra-high-energy cosmic ray but also on the properties of the hadronic interactions. For energies above those achievable in human-made accelerators, hadronic interactions are only accessible through the studies of extensive air showers, which can be measured at the Pierre Auger Observatory. With its hybrid detector design, the Pierre Auger Observatory measures both the longitudinal development of showers in the atmosphere and the lateral distribution of particles that arrive at the ground. This way, observables that are sensitive to hadronic interactions at ultra-high energies can be obtained. While the hadronic interaction cross-section can be assessed from the longitudinal profiles, the number of muons and their fluctuations measured with the ground detectors are linked to other physical properties. In addition to these direct studies, we discuss here how measurements of the atmospheric depth of the maximum of air-shower profiles and the characteristics of the muon signal at the ground can be used to test the self-consistency of the post-LHC hadronic models., Comment: Proceedings of VHEPU 56th Rencontres de Moriond 2022

Abstract

The Auger Muons and Infill for the Ground Array (AMIGA) is an enhancement of the Pierre Auger Observatory, whose purpose is to lower the energy threshold of the observatory down to 10$^{16.5}$ eV, and to measure the muonic content of air showers directly. These measurements will significantly contribute to the determination of primary particle masses in the range between the second knee and the ankle, to the study of hadronic interaction models with air showers, and, in turn, to the understanding of the muon puzzle. The underground muon detector of AMIGA is concomitant to two triangular grids of water-Cherenkov stations with spacings of 433 and 750 m; each grid position is equipped with a 30\,m$^2$ plastic scintillator buried at 2.3 m depth. After the engineering array completion in early 2018 and general improvements to the design, the production phase commenced. In this work, we report on the status of the underground muon detector, the progress of its deployment, and the performance achieved after two years of operation. The detector construction is foreseen to finish by mid-2022.

Abstract

The Pierre Auger Observatory, which is the largest air-shower experiment in the world, offers unprecedented exposure to neutral particles at the highest energies. Since the start of data collection more than 18 years ago, various searches for ultra-high-energy (UHE, E & 1017 eV) photons have been performed, either for a diffuse flux of UHE photons, for point sources of UHE photons or for UHE photons associated with transient events such as gravitational wave events. In the present paper, we summarize these searches and review the current results obtained using the wealth of data collected by the Pierre Auger Observatory., Argentina-Comision Nacional de Energia Atomica, ANPCyT, Consejo Nacional de Investigaciones Cientificas y Tecnicas (CONICET), Gobierno de la Provincia de Mendoza, Municipalidad de Malargue, NDM Holdings, Valle Las Lenas, Australian Research Council, Belgium-Fonds de la Recherche Scientifique (FNRS), FWO, Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPQ) Fundacao de Apoio a Pesquisa do Distrito Federal (FAPDF) Financiadora de Inovacao e Pesquisa (Finep) Fundacao Carlos Chagas Filho de Amparo a Pesquisa do Estado do Rio De Janeiro (FAPERJ) Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP) 2019/10151-2 2010/07359-6 1999/05404-3, Ministerio da Ciencia, Tecnologia, Inovacoes e Comunicacoes (MCTIC), France-Centre de Calcul IN2P3/CNRS Centre National de la Recherche Scientifique (CNRS) Region Ile-de-France Centre National de la Recherche Scientifique (CNRS) Departement Sciences de l'Univers (SDU-INSU/CNRS) French National Research Agency (ANR) LABEX ANR-10-LABX-63 ANR-11-IDEX-0004-02, Federal Ministry of Education & Research (BMBF) German Research Foundation (DFG) Finanzministerium Baden-Wurttemberg Helmholtz Alliance for Astroparticle Physics (HAP) Helmholtz Association Ministerium fur Kultur und Wissenschaft des Landes Nordrhein-Westfalen Ministerium fur Wissenschaft, Forschung und Kunst des Landes Baden-Wurttemberg, Italy-Istituto Nazionale di Fisica Nucleare (INFN) Istituto Nazionale Astrofisica (INAF), Ministry of Education, Universities and Research (MIUR), CETEMPS Center of Excellence, Ministry of Foreign Affairs and International Cooperation (Italy), Consejo Nacional de Ciencia y Tecnologia (CONACyT) 167733 Universidad Nacional Autonoma de Mexico Programa de Apoyo a Proyectos de Investigacion e Innovacion Tecnologica (PAPIIT) Universidad Nacional Autonoma de Mexico, Netherlands-Ministry of Education, Culture and Science Netherlands Organization for Scientific Research (NWO), SURF Cooperative, Poland-Ministry of Education and Science DIR/WK/2018/11 National Science Centre, Poland 2016/22/M/ST9/00198 2016/23/B/ST9/01635 2020/39/B/ST9/01398, Portuguese Foundation for Science and Technology FEDER funds within Programa Operacional Factores de Competitividade through FundacAo para a Ciencia e a Tecnologia (COMPETE), Romania-Ministry of Research, Innovation and Digitization, CNCS/CCCDI UEFISCDI within the National Nucleus Program PN19150201/16N/2019 PN1906010 PNCDI III TE128 PN-III-P1-1.1-TE-2021-0924/TE57/2022 PED289, Slovenian Research Agency - Slovenia P1-0031 P1-0385 I0-0033 N1-0111, Spanish Government FPA2017-85114-P PID2019-104676GB-C32, Xunta de Galicia, European Commission ED431C 2017/07, Junta de Andalucia SOMM17/6104/UGR P18-FR-4314, European Commission, RENATA Red Nacional Tematica de Astroparticulas FPA2015-68783-REDT, Maria de Maeztu Unit of Excellence MDM-2016-0692, United States Department of Energy (DOE) DE-AC02-07CH11359 DE-FR02-04ER41300 DE-FG02-99ER41107 DE-SC0011689, National Science Foundation (NSF) 0450696, Grainger Foundation, Marie Curie-IRSES/EPLANET, European Particle Physics Latin American Network, UNESCO, MSMT CR LTT18004 LM2015038 LM2018102 CZ.02.1.01/0.0/0.0/16_013/0001402 CZ.02.1.01/0.0/0.0/18_046/0016010 CZ.02.1.01/0.0/0.0/17_049/0008422

Abstract

International audience; Here, we point out that an observation of ultrahigh energy cosmic ray (UHECR) photons, “GZK photons”, could provide an upper limit on the level of the extragalactic radio background, depending on the level of UHECR proton primaries (to be determined after a few years of data taking by the Pierre Auger Observatory upgrade AugerPrime). We also update our 2005 prediction of the range of GZK photon fluxes expected from proton primaries.

Abstract

In order to answer the question of whether Schottky barriers on polar ZnO surfaces are different at Zn- and O-terminated surfaces, the interface formation of $n$-type ZnO and different high work function metals and metal oxides (Pt, ${\mathrm{PtO}}_{x}$, and ${\mathrm{RuO}}_{2}$) with Schottky barrier heights of up to 1.5 eV has been studied using photoelectron spectroscopy with in situ sample preparation. The experiments are designed to exclude the effects of substrate reduction and consequent Fermi level pinning by high concentrations of oxygen vacancies. Moreover, by including the Zn LMM Auger emission in the analysis, it is demonstrated that an accurate extraction of barrier heights needs to take into account that the screening of the photoelectron core hole can change in the course of contact formation. The polarization dependence of Schottky barriers, which is important for piezotronic applications, is in most cases dominated by the influence of defects. Reducing the influence of defects, up to $\ensuremath{\sim}240$ meV higher Schottky barriers are revealed on oxygen-terminated surfaces. This is opposite to what has been reported in the literature but agrees with the dependence of barrier heights expected for an incomplete screening of the polarization of ZnO by the electrode as for ferroelectric materials.

Abstract

Science advances 8(22), eabn6848 (2022). doi:10.1126/sciadv.abn6848, Here, we use x-rays to create and probe quantum coherence in the photoionized amino acid glycine. The outgoing photoelectron leaves behind the cation in a coherent superposition of quantum mechanical eigenstates. Delayed x-ray pulses track the induced coherence through resonant x-ray absorption that induces Auger decay and by photoelectron emission from sequential double photoionization. Sinusoidal temporal modulation of the detected signal at early times (0-25 fs) is observed in both measurements. Advanced ab initio many-electron simulations allow us to explain the first 25 fs of the detected coherent quantum evolution in terms of the electronic coherence. In the kinematically complete x-ray absorption measurement we monitor its dynamics for a period of 175 fs and observe an evolving modulation that may implicate the coupling of electronic to vibronic coherence at longer time scales. Our experiment provides a direct support for the existence of long-lived electronic coherence in photoionized biomolecules., Published by Assoc., Washington, DC [u.a.]

Abstract

Ultra-high-energy photons with energies exceeding 1017 eV offer a wealth of connections to different aspects of cosmic-ray astrophysics as well as to gamma-ray and neutrino astronomy. The recent observations of photons with energies in the 1015 eV range further motivate searches for even higher-energy photons. In this paper, we present a search for photons with energies exceeding 2 × 1017 eV using about 5.5 yr of hybrid data from the low-energy extensions of the Pierre Auger Observatory. The upper limits on the integral photon flux derived here are the most stringent ones to date in the energy region between 1017 and 1018 eV., Argentina-Comision Nacional de Energia Atomica, ANPCyT, Argentina-Consejo Nacional de Investigaciones Cientificas y Tecnicas (CONICET) Argentina-Gobierno de la Provincia de Mendoza Argentina-Municipalidad de Malargue Argentina-NDM Holdings, Australian Research Council, Belgium-Fonds de la Recherche Scientifique (FNRS), FWO, Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPQ) Fundacao de Apoio a Pesquisa do Distrito Federal (FAPDF) Brazil-Financiadora de Estudos e Projetos (FINEP) Fundacao Carlos Chagas Filho de Amparo a Pesquisa do Estado do Rio De Janeiro (FAPERJ) Brazil-Sao Paulo Research Foundation (FAPESP) 2019/10151-2 2010/07359-6 1999/05404-3 Brazil-Ministerio da Ciencia, Tecnologia, Inovacoes e Comunicacoes (MCTIC), France-Centre de Calcul IN2P3/CNRS Centre National de la Recherche Scientifique (CNRS) France-Conseil Regional Ile-deFrance France-Departement Physique Nucleaire et Corpusculaire (PNC-IN2P3/CNRS) France-Departement Sciences de l'Univers (SDU-INSU/CNRS) France-Institut Lagrange de Paris (ILP) LABEX ANR-10-LABX-63 ANR-11-IDEX-0004-02, Federal Ministry of Education & Research (BMBF) German Research Foundation (DFG) Germany-Finanzministerium Baden-Wurttemberg Germany-Helmholtz Alliance for Astroparticle Physics (HAP) Germany-Helmholtz-Gemeinschaft Deutscher Forschungszentren (HGF) Germany-Ministerium fur Innovation, Wissenschaft und Forschung des Landes Nordrhein-Westfalen Germany-Ministerium fur Wissenschaft, Forschung und Kunst des Landes Baden-Wurttemberg, Italy-Istituto Nazionale di Fisica Nucleare (INFN) Italy-Istituto Nazionale di Astrofisica (INAF) Italy-Ministero dell'Istruzione, dell'Universita e della Ricerca (MIUR) Italy-CETEMPS Center of Excellence Italy-Ministero degli Affari Esteri (MAE), Consejo Nacional de Ciencia y Tecnologia (CONACyT) 167733, Mexico-Universidad Nacional Autonoma de Mexico (UNAM) Mexico-PAPIIT DGAPA-UNAM, The Netherlands-Ministry of Education, Culture and Science The Netherlands-Netherlands Organisation for Scientific Research (NWO) The Netherlands-Dutch national e-infrastructure The Netherlands-SURF Cooperative, Poland -Ministry of Education and Science DIR/WK/2018/11 Poland -National Science Centre 2016/22/M/ST9/00198 2016/23/B/ST9/01635 2020/39/B/ST9/01398, Portuguese Foundation for Science and Technology Portugal-FEDER funds within Programa Operacional Factores de Competitividade through Fundacao para a Ciencia e a Tecnologia (COMPETE), Romania-Ministry of Research, Innovation and Digitization, CNCS/CCCDI-UEFISCDI, within PNCDI III PN19150201/16N/2019 PN1906010 TE128 PED289, Slovenian Research Agency - Slovenia P1-0031 P1-0385 I0-0033 N1-0111, Spanish Government FPA2017-85114-P PID-2019104676GB-C32, Spain-Xunta de Galicia ED431C 2017/07 Spain-Junta de Andalucia Feder Funds SOMM17/6104/UGR P18-FR-4314 Spain-RENATA Red Nacional Tematica de Astroparticulas FPA2015-68783-REDT Spain-Maria de Maeztu Unit of Excellence MDM-2016-0692, United States Department of Energy (DOE) DE-AC02-07CH11359 DE-FR02-04ER41300 DE-FG02-99ER41107 DE-SC0011689, National Science Foundation (NSF) 0450696, USA-Grainger Foundation USA-Marie Curie-IRSES/EPLANET USA-European Particle Physics Latin American Network USA-UNESCO, Argentina-Valle Las Lenas MSMT CR LTT18004 LM2015038 LM2018102 CZ.02.1.01/0.0/0.0/16_013/0001402 CZ.02.1.01/0.0/0.0/18_046/0016010 CZ.02.1.01/0.0/0.0/17_049/0008422

Kinematics and energy thresholds of interactions are modified once the LIV terms become comparable to the squared masses of the particles involved. Thus, the strongest constraints on the LIV coefficients δi,n tend to come from the highest energies. At sufficiently high energies, photons produced by cosmic ray interactions as they propagate through the Universe could be subluminal and unattenuated over cosmological distances. Cosmic ray interactions can also be modified and lead to detectable fingerprints in the energy spectrum and mass composition observed on Earth. The data collected at the Pierre Auger Observatory are therefore possibly sensitive to both the electromagnetic and hadronic sectors of LIV. In this article, we explore these two sectors by comparing the energy spectrum and the composition of cosmic rays and the upper limits on the photon flux from the Pierre Auger Observatory with simulations including LIV. Constraints on LIV parameters depend strongly on the mass composition of cosmic rays at the highest energies. For the electromagnetic sector, while no constraints can be obtained in the absence of protons beyond 1019 eV, we obtain δγ,0 > -10-21, δγ,1 > -10-40 eV-1 and δγ,2 > -10-58 eV-2 in the case of a subdominant proton component up to 1020 eV. For the hadronic sector, we study the best description of the data as a function of LIV coefficients and we derive constraints in the hadronic sector such as δhad,0 < 10-19, δhad,1 < 10-38 eV-1 and δhad,2 < 10-57 eV-2 at 5σ CL., Argentina — Comisión Nacional de Energía Atómica, Agencia Nacional de Promoción Científica y Tecnológica (ANPCyT), Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET), Gobierno de la Provincia de Mendoza, Municipalidad de Malargüe, NDM Holdings and Valle Las Leñas, Australia — the Australian Research Council, Belgium — Fonds de la Recherche Scientifique (FNRS), Research Foundation Flanders (FWO), Brazil — Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), Financiadora de Estudos e Projetos (FINEP), Fundação de Amparo à Pesquisa do Estado de Rio de Janeiro (FAPERJ), São Paulo Research Foundation (FAPESP) Grants No. 2019/10151-2, No. 2010/07359-6 and No. 1999/05404-3, Ministério da Ciência, Tecnologia, Inovações e Comunicações (MCTIC), Czech Republic — Grant No. MSMT CR LTT18004, LM2015038, LM2018102, CZ.02.1.01/0.0/0.0/16_013/0001402, CZ.02.1.01/0.0/0.0/18_046/0016010 and CZ.02.1.01/0.0/0.0/17_049/0008422, France — Centre de Calcul IN2P3/CNRS, Centre National de la Recherche Scientifique (CNRS), Conseil Régional Ile-de-France; Département Physique Nucléaire et Corpusculaire (PNC-IN2P3/CNRS), Département Sciences de l’Univers (SDU-INSU/CNRS), Institut Lagrange de Paris (ILP) Grant No. LABEX ANR-10-LABX-63- Investissements d’Avenir Programme Grant No. ANR-11-IDEX-0004-02, Germany — Bundesministerium für Bildung und Forschung (BMBF)Germany, Deutsche Forschungsgemeinschaft (DFG), Finanzministerium Baden-Württemberg, Helmholtz Alliance for Astroparticle Physics (HAP), Helmholtz-Gemeinschaft Deutscher Forschungszentren (HGF), Ministerium für Innovation, Wissenschaft und Forschung des Landes Nordrhein-Westfalen, Ministerium für Wissenschaft, Forschung und Kunst des Landes Baden-Württemberg, Italy — Istituto Nazionale di Fisica Nucleare (INFN), Istituto Nazionale di Astrofisica (INAF), Ministero dell’Istruzione, dell’Università e della Ricerca (MIUR), CETEMPS Center of Excellence, Ministero degli Affari Esteri (MAE), México — Consejo Nacional de Ciencia y Tecnología (CONACYT) No. 167733, Universidad Nacional Autónoma de México (UNAM), PAPIIT DGAPA-UNAM, The Netherlands — Ministry of Education, Culture and Science, Netherlands Organisation for Scientific Research (NWO), Dutch national e-infrastructure with the support of SURF Cooperative; Poland — Ministry of Education and Science, grant No. DIR/WK/2018/11, National Science Centre, Grants No. 2016/22/M/ST9/00198, 2016/23/B/ST9/01635, and 2020/39/B/ST9/01398, Portugal — Portuguese national funds and FEDER funds within Programa Operacional Factores de Competitividade through Fundação para a Ciência e a Tecnologia (COMPETE), Romania — Ministry of Research, Innovation and Digitization, CNCS/CCCDI — UEFISCDI, projects PN19150201/16N/2019, PN1906010, TE128 and PED289, within PNCDI III, Slovenia — Slovenian Research Agency, grants P1-0031, P1-0385, I0-0033, N1-0111, Spain — Ministerio de Economía, Industria y Competitividad (FPA2017-85114-P and PID2019-104676GB-C32), Xunta de Galicia (ED431C 2017/07), Junta de Andalucía (SOMM17/6104/UGR, P18-FR-4314), Feder Funds, RENATA Red Nacional Temática de Astropartículas (FPA2015-68783-REDT), María de Maeztu Unit of Excellence (MDM-2016-0692), U.S.A. — Department of Energy, Contracts No. DE-AC02-07CH11359, No. DE-FR02-04ER41300, No. DE-FG02-99ER41107 and No. DE-SC0011689, National Science Foundation, Grant No. 0450696, The Grainger Foundation, Marie Curie-IRSES/EPLANET, European Particle Physics Latin American Network, UNESCO

Abstract

Iron-based catalysts are employed in CO2-FTS due to their ability to convert CO2 into CO in a first step and their selectivity towards higher hydrocarbons in a second CO hydrogenation step. According to the literature, iron carbides represent the active phase for hydrocarbon formation and are claimed to emerge in the presence of CO. We propose nanostructured FeOx films as model systems to assess information about the complex phase transformations during CO2-FTS. Mesoporous hematite, ferrihydrite, maghemite, maghemite/magnetite films were exposed to CO2-FTS atmospheres at 20 bar and 300 °C. Up to three distinct phases were observed depending on the time-on-stream (TOS): a sintered maghemite/magnetite phase, a carbidic core-shell structure, and a low-crystalline, needle-type oxide phase. Our findings indicate that the formation of an intermediary maghemite/magnetite phase, predominant after short TOS (30 h), precedes the evolution of the carbide phase. Yet, even after prolonged TOS (185 h), no full conversion into a bulk carbide is observed.

Abstract

The Pierre Auger Observatory, at present the largest cosmic-ray observatory ever built, is instrumented with a ground array of 1600 water-Cherenkov detectors, known as the Surface Detector (SD). The SD samples the secondary particle content (mostly photons, electrons, positrons and muons) of extensive air showers initiated by cosmic rays with energies ranging from $10^{17}~$eV up to more than $10^{20}~$eV. Measuring the independent contribution of the muon component to the total registered signal is crucial to enhance the capability of the Observatory to estimate the mass of the cosmic rays on an event-by-event basis. However, with the current design of the SD, it is difficult to straightforwardly separate the contributions of muons to the SD time traces from those of photons, electrons and positrons. In this paper, we present a method aimed at extracting the muon component of the time traces registered with each individual detector of the SD using Recurrent Neural Networks. We derive the performances of the method by training the neural network on simulations, in which the muon and the electromagnetic components of the traces are known. We conclude this work showing the performance of this method on experimental data of the Pierre Auger Observatory. We find that our predictions agree with the parameterizations obtained by the AGASA collaboration to describe the lateral distributions of the electromagnetic and muonic components of extensive air showers., Comment: Published version, 23 pages, 15 figures

Abstract

The sources of ultra-high-energy cosmic rays are still unknown, but assuming standard physics, they are expected to lie within a few hundred megaparsecs from us. Indeed, over cosmological distances cosmic rays lose energy to interactions with background photons, at a rate depending on their mass number and energy and properties of photonuclear interactions and photon backgrounds. The universe is not homogeneous at such scales, hence the distribution of the arrival directions of cosmic rays is expected to reflect the inhomogeneities in the distribution of galaxies; the shorter the energy loss lengths, the stronger the expected anisotropies. Galactic and intergalactic magnetic fields can blur and distort the picture, but the magnitudes of the largest-scale anisotropies, namely the dipole and quadrupole moments, are the most robust to their effects. Measuring them with no bias regardless of any higher-order multipoles is not possible except with full-sky coverage. In this work, we achieve this in three energy ranges (approximately 8--16 EeV, 16--32 EeV, and 32--$\infty$ EeV) by combining surface-detector data collected at the Pierre Auger Observatory until 2020 and at the Telescope Array (TA) until 2019, before the completion of the upgrades of the arrays with new scintillator detectors. We find that the full-sky coverage achieved by combining Auger and TA data reduces the uncertainties on the north-south components of the dipole and quadrupole in half compared to Auger-only results., Comment: proceedings of the 37th International Cosmic Ray Conference (ICRC 2021), 12-23 July 2021, Berlin, Germany

Abstract

The new universal sampler for selection of cores of bottom sediments in shallow reservoirs from low-dimensional vessels or from ice is presented. The tube is immersed manually by means of a partitioned boom. The immersion into the sediment depending on its softness/ denseness is produced by pressing or by rotating. For that, the tube is equipped with detachable tips – either a smooth nose cone, or an auger bit, respectively. The tube has a plastic liner inside and an orange peel closing system similar to those used in gravity corers but installed in a different way, taking into account the safety of thin-wall details during drilling. To do this, the orange peel rotating along with the tube is placed fully opened in spacing between the tube and the liner, that excludes its contact with the sample during immersion into the liner. To lock the core, the liner at the beginning of the recovery moves upwards so that the orange peel can close. As a result, it is possible to select cores with undisturbed structure on different types of sediment, except for dense gravel. The efficiency of the new sampler was confirmed by its successful use from motor catamaran and ice in studies of bottom sediments of the Curonian and the Vistula Lagoon and of the 25 m deep lake in the spent amber quarry. The sampler can be used in marine sedimentology, limnology, and geoecology to determine the physico-mechanical, chemical and other characteristics of bottom sediments.

Abstract

The inner-valence Auger electron spectra after the chlorine 2p ionization in the gas phase CHCl3 molecule were investigated both theoretically and experimentally. The total ion yield spectrum exhibits a broad structure at 217 eV, above the Cl 2p ionization threshold, which can be attributed to either a shape resonance or a shake-up. In addition, we have performed a series of high-level ab initio quantum mechanical calculations at the density functional theory level to compute the Auger lines.

Abstract

Aiming at the problems of high-power consumption and insufficient kneading and cutting of roughage in the total mixed ration mixer. In this paper, licorice stems were taken as experimental objects, the horizontal twin-shaft TMR mixer was used to carry out the experimental study. It should be as brief as possible and concise. Through the kneading and cutting process power analysis, determine the influencing factors of kneading and cutting power consumption. The auger speed, processing time and blade type were taken as experimental factors, with standard straw length rate and power consumption as indicators, Box–Behnken test with three factors and three levels was carried out, analysis of variance was performed on the test results, the results show that the significant effect of each factor on the standard grass length is processing time, blade type and auger speed in descending order. The significance of the influence on power consumption from large to small is auger speed, processing time and blade type. The response surface analysis and parameter optimization were carried out, the results show that the auger speed is 20 r/min, the processing time is 29 min, and the blade type is quincunx blade. At this time, the standard straw length was 82.634%; Power consumption 4525.815 kJ, TMR mixer performance reached the best. The results can provide a theoretical basis for the subsequent research and development of TMR mixer.

Abstract

We investigate the implications of the current data regarding large scale anisotropies, and examine to what extent they can be used to constrain the origin of UHECRs and the astrophysical parameters of the source scenarios. We discuss the possibility of observing an associated anisotropy of the composition, the potential benefit of the separation of the different nuclear components and the interest of observing the UHECR sky with larger exposure future observatories. We simulate UHECR sky maps for various astrophysical scenarios satisfying the current observational constraints, taking into account the energy losses of the UHE protons and nuclei and their deflections by intervening magnetic fields. We investigate scenarios in which the UHECR source distribution follows that of the galaxies, varying the source composition and spectrum, the source density and the magnetic field models. We apply similar analyses as those used by the Auger collaboration. We find that: i) reproducing the observed dipole anisotropy and its energy evolution is relatively easy within our assumptions; ii) this agreement can be obtained with different sets of assumptions on the astrophysical parameters, and is thus not, at this stage, very constraining for UHECR source scenarios; iii) the actual reconstructed direction of the dipole appears non natural in essentially all scenarios investigated, and challenges their main assumptions on the source distribution or the assumed magnetic field configuration, especially in the Galaxy; iv) except for protons, the energy range in which the GZK horizon strongly reduces is a key target for anisotropy searches for each given nuclear species; v) The composition anisotropy naturally expected in our models is unlikely to account for that recently reported by Auger unless the observed amplitude is a strong positive statistical fluctuation of an intrinsically weaker signal., Comment: 39 pages, 32 figures

Abstract

Quantum dot light-emitting diodes (QLEDs) are one of the most promising candidates for next-generation displays and lighting sources, but they are barely used because vulnerability to electrical and thermal stresses precludes high brightness, efficiency, and stability at high current density (J) regimes. Here, bright and stable QLEDs on a Si substrate are demonstrated, expanding their potential application boundary over the present art. First, a tailored interface is granted to the quantum dots, maximizing the quantum yield and mitigating nonradiative Auger decay of the multiexcitons generated at high-J regimes. Second, a heat-endurable, top-emission device architecture is employed and optimized based on optical simulation to enhance the light outcoupling efficiency. The multilateral approaches realize that the red top-emitting QLEDs exhibit a maximum luminance of 3 300 000 cd m-2 , a current efficiency of 75.6 cd A-1 , and an operational lifetime of 125 000 000 h at an initial brightness of 100 cd m-2 , which are the highest of the values reported so far.

Abstract

Several experiments around the world, like the ground-based observatories Pierre Auger and Telescope Array, and soon the space telescope JEM-EUSO, are investigating ultra-high-energy cosmic rays, trying to solve the mystery of their origin. The mass composition of these particles is a key piece of information crucial for a better understanding of the problem. Yet it cannot be observed directly but rather inferred from the simultaneous measure of the energy $$E_0$$ of the primary particle and the atmospheric depth $$X_{\mathrm{max}}$$ of its shower maximum. The conversion of ( $$E_0, X_{\mathrm{max}}$$ ) into a primary mass can only be achieved by air-shower simulation. The paper investigates this question through detailed Monte Carlo calculations of air showers initiated by ultra-high-energy cosmic rays of $$10^{18}$$ – $$10^{20}$$ eV. The calculations were carried out using the code CONEX in combination with different up-to-date hadronic interaction models. The obtained results are compared to the most recent data from the current experiments.

Abstract

Ice cores are excellent archives for obtaining long and continuous 10Be records. However, traditional ice core 10Be measurements required a lot of ice (0.5–1kg) and often needed to be connected to a large and costly ice core project. These reasons have been the factors limiting the number and variety of 10Be projects and data. In this paper, we show measurements of 10Be on small samples (∼45g) of continuous auger ice chips from a borehole at Little Dome C (LDC), East Antarctica. The sample preparation method for 10Be accelerator mass spectrometry (AMS) was tested and optimized using test samples (∼50g) including well-mixed surface ice chips from the LDC site, snow collected in Lund (Sweden) and frozen Milli-Q water. The results show that our small ice samples should be processed without ion exchange filtration of the melt water and cleaning the subsequent Be(OH)2 precipitate. In addition, co-precipitating Be with Fe led to more reproducible measurement currents and offer the potential for higher efficiency and precision via longer measurement time. We applied the established preparation method to measure 10Be on 76 samples of the auger ice chips. The resulting 10Be concentration record for the period from 1354 to 1950 CE agrees well with the 10Be concentration in a South Pole ice core and the global 14C production rate and thus reflects well the atmospheric production signal of 10Be. We also observed insignificant mixing among the ice chip samples during the process of drilling and retrieving the ice. Therefore, the new ice chip samples are promising for assessing the long-term changes in 10Be deposition at different ice core sites. A wide application of this novel ice chip samples will increase the variety of 10Be records which will help to improve the assessment of long-term solar and geomagnetic shielding of galactic cosmic rays., Results in Geochemistry, 5

Abstract

The continuous flight auger (CFA) piling technique is commonly used where the presence of groundwater or potentially collapsible material reduces the cost-effectiveness of bored piling techniques. Whilst generally considered a soil replacement technique, the process of pumping concrete under pressure during the pile installation can result in a significant improvement of the surrounding soil, particularly in low strength soil conditions. In this study, a case study is analyzed. An oil storage tank was intended to be constructed on soft clay in southern Iraq. The tank has a diameter of 46 m. Cone penetration test, drilling boreholes, and field tests have been conducted in the tank site. A decision was made to improve the mechanical properties of soft clay of the site by CFA piles before construction of the tank. The depth of CFA pile constructed is 16 m, with a diameter of 0.5 m and spacing between piles is 4.2 m. Three types of in-situ tests have been conducted: Conventional plate load test on the soil before and after improvement; large plate load test for soil after improvement; and pile load test on CFA pile. It was concluded that construction of CFA piles shows an increase in the bearing capacity by about 110% for the soil directly around piles and 70% for soil within 2 m from the center of piles. Large plate load test result for the pile with surrounding soil revealed that the ultimate bearing capacity increases to 500 kN/m2. So that the overall loading area showed an increase in the bearing capacity of about 350% when CFA piles are constructed.

Abstract

As an alternative to existing approaches, a universal mobile robotic platform equipped with a auger heat-electromechanical converter is proposed. The proposed converter uses an external rotor-auger for rotary motion and an internal stationary shaft for sampling without soil rotation. The data obtained on the spatial distribution of magnetic induction and eddy current density in the active part of the auger heat-electromechanical converter are an important stage on the way to further numerical experiments, in particular, to perform a series of accurate postprocessor calculations to obtain mechanical characteristics. This, in turn, will contribute to development of auger converters optimal design for universal mobile robotic platforms, as well as a strategy for controlling their movement.

Abstract

Two different phases of the transition-metal dichalcogenide and molybdenum ditelluride (1T′-MoTe2 and 2H-MoTe2) were grown by chemical vapor transport. Oxygen-free surfaces were generated by exfoliation in air and then analyzed by x-ray photoelectron spectroscopy. High-resolution core and valence and Auger spectra were acquired for both materials including Te 3d, Te 4d, Te MNN, Mo 3d, and valence band spectra. Differences in Te 3d and Mo 3d peak positions that were previously reported were confirmed, and asymmetry on the metallic 1T′-phase was documented in the Te 3d, Te 4d, and Mo 3d spectra that could prove useful in identifying mixtures of these materials.
