Description
Summary:The results of studying the temperature-induced polymorphic phase transformations in Cu 1.50 Zn 0.30 Te and Cu 1.75 Cd 0.05 Te single crystals are presented. The single crystals have been investigated in the range of 290–1100 K using X-ray diffraction analysis. The temperature dependences of the unit-cell parameters, X-ray density, and coefficients of thermal expansion for each polymorphic modification of Cu 1.50 Zn 0.30 Te and Cu 1.75 Cd 0.05 Te single crystals are presented. The influence of cationic substitution (replacement of Cu 2+ with Zn 2+ and Cd 2+ cations) on the phase-formation processes, number of polymorphic modifications, and temperature of structural phase transition in single crystals of these solid solutions is demonstrated.
