Abstract

Charge carrier transport through the probe-sample junction can have substantial consequences for outcomes of electrical and electromechanical atomic-force-microscopy (AFM) measurements. For understanding physical processes under the probe, we carried out conductive-AFM (C-AFM) measurements of local current-voltage (I-V) curves as well as their derivatives on samples of a mixed ionic-electronic conductor Li1-xMn2O4 and developed an analytical framework for the data analysis. The implemented approach discriminates between contributions of a highly resistive sample surface layer and bulk with the account of ion redistribution in the field of the probe. It was found that with increasing probe voltage, the conductance mechanism in the surface layer transforms from Pool-Frenkel to space-charge-limited current. The surface layer significantly alters the ion dynamics in the sample bulk under the probe, which leads, in particular, to a decrease of the effective electromechanical AFM signal associated with the ionic motion in the sample. The framework can be applied for the analysis of mechanisms of electronic transport across the probe/sample interface as well as the role of the charge transport in the electric field distribution, mechanical, and other responses in AFM measurements of a broad spectrum of conducting materials., Comment: 31 pages main text, 35 pages Supporting Information

Abstract

This work is devoted to the visualization and evolution of κ1-phase particles in annealed proton exchange (PE) waveguides. It is well-known that the presence of κ1-phase particles in optical waveguides leads to an increase in their optical losses and instability of operation. It has been found that precipitated κ1-phase particles propagate through the whole waveguide depth and have perpendicular orientation to the surface of the lithium niobate crystal. These results are important for fast quality control of annealed PE waveguides. [ABSTRACT FROM AUTHOR]

Abstract

The creation of the periodical domain patterns with a submicron period in lithium niobate on insulator (LNOI) wafers is a key problem for nonlinear-optical applications, including second harmonic generation, backscattering optical parametric oscillator, etc. We have experimentally studied the domain formation and evolution during local polarization reversal in Z+ LNOI wafers with a metal bottom electrode. It has been shown that domain growth occurs by the formation of the spikes at the charged domain wall (CDW). The complicated shape of isolated domains with a jagged CDW has been revealed. The obtained weak domain-domain interaction has been attributed to effective bulk screening by charge injection. The revealed dependence of the domain sizes on humidity caused by the adsorbed water layer should be taken into account during periodical poling. © 2020 Author(s).

Abstract

Cerium oxide (CeO) has a wide range of different applications such as gas sensing, water splitting and others. CeO is an attractive alternative to yttria-stabilized zirconia as an electrolyte for low-temperature fuel cells because of its high ionic conductivity, low reactivity and good chemical compatibility with many mixed conducting cathode materials [1]. The equipment of the Ural Center for Shared Use"Modern nanotechnology" UrFU was used. This research was made possible in part by RFBR (Grant No. 15-52-06006 MNTI_a). This work was supported by the Israeli Ministry of Science and Technology within the program of Israel Russian Federation Scientific Collaboration, Grant No. 12421-3.
