| Popis: |
The compound CuInZnSe3 was synthesized, the crystal structure was investigated by X-ray diffraction and thermal properties was investigated by differential scanning calorimetry analysis. It was found that, under normal conditions, the crystal structure of this compound corresponds to cubic symmetry with the space group F-43m (216). The temperature dependence is obtained at a constant rate of heat treatment of the heat flow in the temperature range T=30-900oC. The observed endothermic effects at T=43, 600 and 756oC are explained by the resonance of thermal vibrations of atoms in the crystal structure of the CuInZnSe3 compound and the release of relatively weakly bound atoms. Keywords: X-ray diffraction, semiconductors, chalcogenides. |
