Paper Abstract

The experimental fact of an essential increase in optical, radiation and degradation firmness of heterogeneous optoelectronic material CdS-PbS is explained in terms of a difference in defect diffusion intensification under irradiation in the wide- and the narrow-band-gap components of the material. A quantity model of the firmness is proposed, and results of computer simulations performed in accordance with it are included which show that under exposure to optic and other kinds of radiation the mentioned difference in defect diffusion intensification makes the defects accumulate in the narrow-band-gap inclusions of CdS- PbS, which in turn leads to the increase in the firmness of the material.
