SOLUBILITY LIMIT OF NI IN CD1-XNIXTE CRYSTALS

The Cd1-xNixTe crystals were grown by the Bridgman method. The investi gated samples were cut from five different ingots with nominal content s of nickel varied from 0.005 to 0.05. The investigations were perform ed using X-ray powder diffraction method and energy dispersive and wav elength dispersive electron microprobe analysis. The samples were also examined in a scanning electron microscope. Examinations of wavelengt h dispersive electron microprobe analysis show that the actual content s of nickel differ from the nominal values. The solubility limit of ni ckel was determined to be x = 0.005. The precipitates of NiTe were fou nd in samples of a greater content of nickel. Their dimensions were be tween 5 to 90 micrometers. X-ray powder diffraction measurements did n ot reveal ally significant change of the lattice constant of investiga ted crystals in comparison with pure CdTe.
