Studies on Semiconductor Structures, Laser-Induced Oxidation and Orientationally-Disordered Crystals

摘要

This report deals with the following areas: (1) Theoretical and experimental studies of non-periodic superlattices, particularly Fibonacci structures; (2) Raman scattering studies of shallow acceptors (Be) in Gallium Arsenides quantum wells; (3) Enhanced Raman scattering by optical phonons in GaAs superlattices; (4) Coupling between Landau level excitations and inter-subband transitions in quantum wells induced by tilted magnetic fields; and (5) Dielectric studies of phase transformation in orientally disordered crystals.
