Abstract :
Mapping of single crystals of Cd(1-x/)Znsub x/Te (x=0.2) grown in Russia by the high pressure vertical Bridgman method, (HPVBM) under argon pressure of 2 to 10 MPa was performed using X-ray fluorescence (XRF), X-ray diffraction (XRD), photoluminescence (PL) and leakage current uniformity. The crystals were more uniform in Zn composition than US produced material but had a poorer crystallinity and in the best case could only count nuclear radiation. Differences in the material properties between Russian and US material will be described
