Abstract

Polycrystalline (Cd,Cr)Te ingots with 2.5, 5, and 25 at.% of nominal chromium content were prepared by alloying the mixture of elemental Cd, Te, and Cr2Te3 salt. The alloys were studied by means of scanning electron microscopy, X-ray diffraction, and energy dispersive X-ray spectroscopy methods in order to determine their crystallinity and phase composition. It was found that the ingots of the lowest doped material are composed of continuous CdTe:Cr host matrix with embedded Cr-related second-phase particles. With the exception of zinc-blende type Cd1−x Cr x Te, the grains of Cr–Te intermetallic compounds with μm-sized particles of pure Cr are solidified from the higher-doped melt. The mechanism of their formation was examined on the basis of the phase diagram for the Cr–Te system. Chromium solubility limit in the cadmium telluride lattice was estimated to be about 1.5 at.%.
