“…For II-VI cation solid solutions, clustering tendencies and phase separations were theoretically predicted and, in some cases, experimentally investigated [10,[16][17][18][19][20][21][22][23][24][25][26]. Contrary to this, ordered phases [27,28] were described and the occurrence of ferroelectricity in Cd 1−x Zn x Te (0.04 ≤ x ≤ 0.45) [29] should be explained by an (at least short-range) ordering of the Zn atoms in the Cd sublattice. A small rhombohedral deviation from cubic symmetry in Cd 0.78 Zn 0.22 Te was reported [30].…”

Microhardness H of Cd 1−x Zn x Te bulk crystals (0 ≤ x ≤ 1) was investigated by the Vickers pyramid indentation. The H (x ) curve has a pronounced peak at x ≈ 0.75. In order to investigate a supposed phase separation, samples were annealed at 503 K, 558 K and 621 K for four weeks and at 896 K for one week under suitable partial vapour pressures. In all of them, neither the hardness was essentially altered nor any additional phases, except the solid solution, were found by x-ray analysis and electron diffraction. Nevertheless, the occurrence of nanometer-size clusters of either different structural phases or chemical compositions cannot be excluded.
