Samples of CdTe-based crystals were characterized. Elemental and phase composition of samples were determined. Microhardness of samples was studied on two perpendicular surfaces. It is shown that in crystals with main CdTe phase and varied dopants the mechanical anisotropy is not observed. In crystals with main CdZnTe the anisotropy of microhardness is observed, it is connected with different lengths of Cd–Te and Zn–Te bonds, which results in nonsymmetrical distortions of crystal lattice. Difference in microhardness of CdTe crystals observed in work is explained by difference of structural parameters.
Podkur et al. (Wed,) studied this question.
