Results of lattice-dynamical calculations of the GaAs/AlAs superlattice grown along the [012] direction are compared with Raman-scattering data. Confined phonon modes and the in-plane (interfacelike) optical modes are clearly observed at frequencies in excellent agreement with theoretical predictions. The confined phonons of the [012]-oriented superlattice have mixed longitudinal and transverse character, as a consequence of the low symmetry of this superlattice (C2 point group). Special emphasis is placed on the angular dispersion and mixed polarization of superlattice modes.
