Phonon modes in GaAs-AIxGaI\_xAS superlattices simplify when the phonon wavevector q is perpendicular to the plane of the layers. We have studied such modes using a Raman back-scattering technique on SL's grown by MBE. The results are consistent with simple ideas of LA phonon freedom and hO phonon c

## Recent research of superlattlces and multiple quantum wells has generated considerable interest in the optical waveguiding properties of these structures for optoelectrontc applications. As a result we present a theoretical study of the index of refraction of superlattices and determine its va
We report the results of photoinduced absorption (PA) measurements in the energy range appropriate for transitions between the heavy holes (hh) and the spin orbit split-off valence-band holes (ao), in samples of undoped, bulk GaAa and GaAa/AlGaAa multiple-quantum-wells (MQW). The bulk GaAa hh-so abs
