Abstract

It has been shown the evidence for the energy location of low-temperature photoluminescence (PL) of bound exciton complexes lines can be used as a technique of internal stress diagnostic in high quality bulk CdTe the substrates material for epitaxial growth photosensitive HgCdTe layers. The obtained deformation dependencies of the energy location and PL lines intensities allow us to estimate the value and sign of elastic stresses as well as defects type.
