Abstract :
It has been shown that isovalent doping by tellurium positively affects the structural perfection of ZnSe crystals related to the completeness of the wurtzite–sphalerite phase transition. The optimum concentration range of tellurium in ZnSe crystals is 0.3–0.6 mass %. X-ray diffraction studies have shown that in ZnSe1−xTex crystals at tellurium concentrations below 0.3 mass % twinning and packing defects occur, while tellurium concentrations above 0.6 mass % lead to formation of tetragonal crystal lattice.
