Many of the important properties derive from the tetrahedral bonding and the valency. Band structure calculations, have established that the zin

Moreover the incorporation of impurities and their special behaviour is decisive for most of the technical devices based on II–VI-compounds.

They appear to be randomly orientated in the glass and of a fairly uniform size distribution. Due to the optical absorption characteristics of the semiconductor crystallites these glasseshave a sh
