Role of background O and Cu impurities in the optics of ZnSe crystals in the context of the band anticrossing model

Abstract:

A new interpretation of self-activated luminescence spectra of II–VI compounds is suggested. This interpretation is based on the theory of the conduction-band splitting induced by oxygen isoelectronic impurity and makes it possible to interpret, from a general viewpoint, the nature of spectral bands whose origin was not clear up to now. The discussion is based on extensive previously obtained experimental material and is illustrated by specific examples necessary for the statement of the problem.
