Abstract
CdTe films of different compositions were grown by the chemical molecular-beam deposition method. The activation energy and the nature of deep levels in relation with the composition of films based on the temperature dependence of electroconductivity are defined, and the influence on these levels of heat treatment process in CdCl2 solution has been studied. Deep levels with the following activation energies are defined: Ev +0.31 eV; Ev + 0.42 ± 0.03 eV; Ec–0.44 ± 0.01 eV; Ec–0.28 eV; Ev + 0.24 ± 0.01 eV.
