Abstract
Lattice properties and elastic parameters of zinc-blende CdTe are determined from a pseudopotential approach. The pressure dependence of the studied properties is examined and discussed. At zero pressure, the accord between our findings and those of the literature is found to be reasonable. Upon compression, all features of interest have shown a monotonic behavior. A larger cleavage energy in CdTe on (110) plane has been predicted when pressure is applied. Moreover, it is found that CdTe becomes more resistant to the transverse deformations and behaves in a brittle manner at all pressures being considered here. Besides, our results show that the hardness becomes better under compression reducing thus the damaging effect on the dislocations operational performance and degradation behavior induced during the devices fabrication.
