Structural defects and band-structure parameters of CdAs2, ZnAs2, Cd1 − x Zn x As2, and Zn1 − x Cd x As2 single crystals

  • 90 Accesses

Abstract

Structurally perfect CdAs2, ZnAs2, Cd1 − x Zn x As2, and Zn1 − x Cd x As2 single crystals have been grown, and the main parameters of their band structure have been determined. We have proposed band structure models for the crystals and presented evidence in favor of the models of structural defects responsible for the donor and acceptor levels in CdAs2, ZnAs2, Cd1 − xZn x As2, and Zn1 − x Cd x As2.
