Comparative study of bulk Hg0.8Cd0.2Te crystals grown from initial components of varying purity

Abstract

Bulk Hg0.8Cd0.2Te crystals still are widely used as a base material for manufacturing IR photoreceivers for the 8-14 micrometers wavelengths range. As these purposes need the material with high mobility of electrons and very low concentration of impurities, problems of purity of the components, used for preparation of it, acquire prime significance.
