GROWTH OF TERNARY AND QUATERNARY ZNSE COMPOUNDS WITH TRANSITION-METALS BY CHEMICAL-VAPOR TRANSPORT

Halogen transport method was applied to grow the crystals of solid sol utions of ZnSe and transition metals at the temperature far below the melting point and phase transition temperature. The large crystals of ZnMnSe, ZnFeSe, ZnNiSe and ZnFeSSe were obtained. The technological pa rameters and shape of the quartz reactor were chosen for growth of a l arge crystal by self-nucleation; the transparent quartz furnace enable d the control of nucleation by visual observation. The parameters of c rystal growth were determined. The crystal quality was estimated by X- ray diffraction method. The composition of crystals was determined by electron microprobe analysis and energy dispersive X-ray fluorescence analysis.
