Abstract

Infrared reflectivity spectra of GaAs/AlGaAs thick multiple heterostructures in the far-infrared range up to 450 cm-1 have been investigated. A big influence of the buffer layer in the transparency region between the two 'Reststrahlen' bands, of GaAs and AlAs, is observed. It was shown that a simple analysis of experimental data with an iterative method, performed in the effective medium approximation, allows a very accurate determination of the structural parameters not only of the superlattice but also of the buffer layer.
