چکیده

Magnetotransport measurements are performed on an aluminum thin film grown on a GaAs substrate. A crossover from electron- to hole-dominant transport can be inferred from both longitudinal resistivity and Hall resistivity with increasing the perpendicular magnetic field B. Also, phenomena of localization effects can be seen at low B. By analyzing the zero-field resistivity as a function of temperature T, we show the importance of surface scattering in such a nanoscale film.

Characteristic of P-type AlAs/GaAs Bragg Mirrors Grown by MBE on (100) and (311)A Oriented Substrates

P-type GaAs/AlAs distributed Bragg mirrors have been grown using molecular beam epitaxy on (100) and (311)A GaAs substrates in a similar conditions. A comparison of I-V measurements shows that the resistance of the ungraded mirrors grown on the (311)A substrate is 35 times lower than those grown on the (100) substrate with similar structure. The effective barrier heights for both (311 )A and (1...

Atmospheric oxygen in Mn doped GaAs/GaAs(0 0 1) thin films grown by molecular beam epitaxy

Mn doped GaAs thin films were grown using molecular beam epitaxy at high and low substrate temperatures. The elemental concentration depth profiles in the thin films were determined by using Auger electron spectroscopy combined with ion etching. The Mn concentration is higher near the surface and then decreases with depth for films grown at high substrate temperatures. The Mn concentration prof...

Electrical and optical studies of GaMnAs/GaAs(0 0 1) thin films grown by molecular beam epitaxy

GaMnAs/GaAs films were grown via molecular beam epitaxy using both low and high substrate temperatures. The films were investigated using Hall effect and photoluminescence (PL) measurements from 8 to 300K. The carrier concentrations in the samples grown at a low substrate temperature are greater than those in the samples grown at a high substrate temperature. The PL spectra show a GaAs exciton ...

Deposition and Characterizations of ZnO Thin Films on Al2O3 (0001) Sub- strates with III-Arsenide Intermediating Layers

ZnO thin films have been grown by radio-frequency magnetron sputtering on c-plane sapphire substrates with III-V (i.e., GaAs and InAs) intermediate layers. The intermediate layers were grown by molecular beam epitaxy. Structural and optical properties were studied by X-ray diffraction (XRD) and Raman scatterings. The growth orientations of the ZnO/III-V/c-sapphire heterostructures were determin...

HIGH RESOLUTION X-RAY MEASUREMENTS OF STRAIN-MEDIATED DIFFUSION IN CuInSe2, P. Fons, S. Niki, A. Yamada, M. Uchino and H. Oyanagi, pp. 201-211

CuInSe2 is a direct bandgap material that assumes the chalcopyrite structure (space group I4̄2d). Due to its large optical absorption coefficient (α ∼ 10 cm−1), its use in thin film polycrystalline solar cells is an active research topic. As most of the research effort to date has been applied directly to polycrystalline film formation for use in solar cell applications and relatively little att...
