Inelastic Light Scattering by Phonons and Electronic Excitations in Low-Dimensional Semiconductor Structures

摘要

Various aspects of inelastic light scattering studies of low-dimensional semiconductor structures are discussed. This includes anisotropy of phonon dispersion in GaAs/AlAs superlattices, interface phonons in Si/Ge superlattices and electronic excitations in quantum wires and dots. Many of these studies require Raman scattering with high spatial resolution.
