Abstract
We consider the propagation of acoustic waves in Si-based heterojuncti ons (HJs), quantum wells (QWs) and superlattices (SLs) grown in arbitr ary directions, and present a general formalism for obtaining wave vel ocities, selection rules, and efficiency of Raman scattering (RS) and Brillouin scattering (BS)by folded acoustic-phonons. Results based on nine different directions for the phonon wavevector are tabulated.
