Abstract

We have found that the local density of states fluctuations (LDOSF) in a disordered metal, detected using an impurity in the barrier as a spectrometer, undergo enhanced (with respect to SdH and dHvA effects) oscillations in strong magnetic fields, omega _c\tau > 1. We attribute this to the dominant role of the states near bottoms of Landau bands which give the major contribution to the LDOSF and are most strongly affected by disorder. We also demonstrate that in intermediate fields the LDOSF increase with B in accordance with the results obtained in the diffusion approximation., Comment: 4 pages, 4 figures

Abstract

We present an experimental and theoretical study of electron tunnelling through quantum dots which focusses the attention on the amplitude of the current peaks as a function of magnetic field. We demonstrate that the amplitudes of the current peaks in the tunnelling spectra show a dramatically different behaviour as a function of the magnetic field, depending on the angular momentum of the dot state through which tunnelling occurs. This is seen in the non-monotonic behaviour of the current amplitude in magnetic field. Furthermore, the magnetic field severely hinders tunnelling through states with angular momentum parallel to the field, and in some cases it makes it altogether impossible. This type of investigation allows us to directly probe the details of the confined wave functions of the quantum dot., Comment: 4 pages, 4 figures changed contents and figures, added new data

Abstract

Raman scattering measurements on low temperature GaAs layers were presented. The transition from diluted As in the GaAs matrix to the small As clusters formed after annealing was examined. Transmission electron microscopy enabled the quantitative measurement of the strain and confinement effect of c-As clusters of low temperature GaAs. This suggested the possibility of using the nondestructive optical probe at room temperature to quickly determine the mean cluster diameter, which was shown to be a significant parameter for the electrical and optical properties of low temperature III-V materials.

Abstract

Raman scattering by coupled phonon-intersubband plasmon excitation in Si delta-doped GaAs is investigated. The symmetry of the coupled models is determined according to the selection rules and their signature by using the difference Raman scattering. The results, calculated theoretically in the frame of the dielectric response theory, are in agreement with those obtained from the experimental spectra. The results provide the proof for electron localization in the nearly regions of the doped sheet and enable the estimation of the electron gas's spatial extent.

12. In-plane photovoltage and photoluminescence studies in sequentially grown GaInNAs and GaInAs quantum wells.

Abstract

We have investigated in-plane photovoltage (IPV) and photoluminescence (PL) in sequentially grown Ga[sub 0.8]In[sub 0.2]As/GaAs and Ga[sub 0.8]In[sub 0.2]N[sub 0.015]As[sub 0.985]/GaAs quantum wells. Temperature, excitation intensity, spectral and time dependent study of the IPV, arising from Fermi level fluctuations along the layers of the double quantum well structure, gives valuable information about the nonradiative centers and hence about the optical quality of the GaInNAs quantum well. It also provides information about the radiative transition energies in all the layers. In order to obtain either the trap activation energies and the detrapping rates of photogenerated carriers in the GaInNAs the IPV results are analyzed in terms of a theoretical model based on random doping fluctuations in nominally undoped multilayer structures. The PL results are analyzed in terms of the band anticrossing model to obtain the electron effective mass from the coupling parameter C[sub NM]. [ABSTRACT FROM AUTHOR]

26. Enhanced fluctuations of the tunneling density of states near the bottom of a Landau band measured by a local spectrometer

Abstract

We have found that the local density of state fluctuations (LDOSF) in a disordered metal, detected using an impurity in the barrier as a spectrometer, undergo enhanced (with respect to Shubnikov-de Haas and de Haas-van Alphen effects) oscillations in strong magnetic fields, omega(c)tau greater than or equal to 1. We attribute this to the dominant role of the states near the bottom of Landau bands which give the major contribution to the LDOSF and are most strongly affected by disorder. We also demonstrate that in intermediate fields the LDOSF increase with field B in accordance with the results obtained in the diffusion approximation.
