Abstract
Transmission spectra of GaAs-AlAs superlattices (SL's) at oblique incidence are calculated from the SL effective medium theory (EMT) to study the phonon anisotropy. Additional phonon spectral features due to SL anisotropy are seen only in the p-polarized (E field in the plane of incidence) spectrum, but not in the s-polarized (E field perpendicular to the plane of incidence) spectrum. The effect of interface roughness and the layer thickness ration on the dielectric response, interference effects in SL structure, and the validity of EMT are discussed. The results have very important implications for infrared experiments and SL structural characterizations.
