Substrate/layer relationships in II-VIs

摘要

This review explores the scope of substrate/layer relationships in II-VI epitaxy. In addition to the lattice parameter mismatch, other important factors such as valence mismatch, polarity and thermal expansion match are condidered. In some cases the lattice parameter mismatch is not the dominant factor in determining material quality such as ZnSe on GaAs. The ideal for high quality epialyers is to use lattice matched II-VI substrates but these have not always been available and alternative substrates have in some cases looked more attractive.
