Abstract
We propose a new technology for the formation of an energy barrier on crystals of Cd1 − x Mn x Te solid solutions. Rectifying photosensitive heterostructures of the intrinsic oxide-Cd1 − x Mn x Te (x = 0.6−1) type have been obtained for the first time by means of thermal oxidation. Stationary current-voltage characteristics and relative quantum efficiency spectra of these heterostructures have been measured. The energy spectrum and the character of interband transitions in Cd1 − x Mn x Te are discussed. It is shown that the thermal oxidation process can be used for the fabrication of heterophotoconverters based on single crystals of dilute magnetic semiconductors of the Cd1 − x Mn x Te system.
