Radiative Recombination in Cadmium Telluride Crystals,et the majority of the observed luminescence lines and bands. A study was made of the strength of the electron — phonon interaction in optical transitions as a function of the nature of the centers involved. The profiles of the luminescence bands resulting from the recombination at deep levels were explained.

The explanation of the edge luminescence was based on a donor-acceptor model of radiative transitions at local levels associated with intrinsic lattice defects.

These luminous regions were due to a new type of instability called ionization domains. An analysis was made of the processes of impact ionization in high fields, which can generate and maintain space-charge regions in a crystal. Quantitative estimates based

Investigation of the Energy Band Structure of Semiconductors by Differential Optical Methods,sults were used to determine the gaps between the energy bands and the values of the spin — orbit splitting of the valence band at the symmetry points Γ, L, and A of the Brillouin zone. Single crystals of CdTe were studied and it was found that the Coulomb interaction between electrons and holes sho

It is shown that if t. ⪝ ., the luminescence is delayed after the end of excitation and this delay can be used to calculate the nonradiativ
