Paper Abstract

Raman spectroscopy is a widely applied technique for investigating the dynamical and structural properties of atomic-layer semiconductor superlawces. The low-frequency acoustic phonons in such structures are influenced by the average lattice properties, the overall periodicities within the structure, and the boundary conditions, whereas the optic phonons are sensitive to the local structure, the nature of the interfaces, and the intralayer strain. Examples taken from recent studies of phonons in thin layer superlattices composed of GaAS/AlAS, InAs/GaSb and SilGe are used to demonstrate the usefulness of the Raman technique.
