Abstract
A theory of nonresonant Raman scattering from interface phonons in GaA s/AlAs superlattices is described. The linear-reponse functions of the phonon-polariton electric field to the polarization induced by the li ght in the superlattice sample are derived. The electric-field Green's functions are used to determine the Raman-scattering cross section an d spectral intensities. The strength of the scattering from each of th e four interface modes agrees well with experimental results for backs cattering from a (110) surface.
