Abstracts

EN

The electrical properties of single Cd_{1 - x}Mn_{x}Te (x= 0.07 - 0.39) crystals with a resistivity of ≈ 10^8 Ω cm at 300 K have been studied. The electrical conductivity is explained in the terms of statistics of electrons and holes in a semiconductor taking into account the compensation process in impurity-defect complexes. The energy of ionization and the degree of compensation levels have been found.
