Abstract

The new technology of energy barrier fabrication by thermal treatment of Cd_1-xMn_xTe solid solution crystal wafers was proposed. By the first time the Ox/Cd_1-хMn_хTe (х=0.00–0.70) heterostructures with rectifying and photosensitive properties was fabricated. The relative quantum efficiency of photoconversion of fabricated by the firs time heterostructures was investigated. The nature of the interband optical transitions and values of the band gap in Cd_1-xMn_xTe was determined.
