Abstract

The phonon spectra of semiconductor superlattices along the growth direction are studied by means of a one-dimensional approach with “long range” interplanar force constants derived from ab initio interplanar forces for the bulk components. Results are shown for frequencies and displacements of , and (001) superlattices, with particular emphasis on the presence of resonant modes and of interface modes of microscopic origin, and for confined optical modes and surface modes in finite (001) superlattices.
