Abstract
We report on low-temperature (77 K) far infrared attenuated total refl ection (ATR) spectroscopic measurements on a short period Ga4s/AlAs su perlattice, and discuss the optics of the modes observed. We assess th e significance of the ATR technique for determining superlattice phono n parameters. We model the results using a linear chain model that inc orporates the effects of interface roughness; it appears that this mod el is correctly modelling the phonon response.
