ABSTRACT

The electrical properties of In0.93Sm0.07Se monocrystalline irradiated in the temperature interval 142-294K with Dγ=(50,70,80,90 and 100) krad were studied. When irradiated with γ-quanta with a dose 50 krad In0.93Sm0.07Se crystals. Electrical conductivity decreases due to compensation of uncontrolled defect centers. At subsequent high doses of radiation, no additional defect centers are formed, but the concentration of the previous centers increases, which leads to an increase in electrical conductivity. The activation energy of charge carriers decreases with increasing dose of γ-irradiation. In0.93Sm0.07Se monocrystalline semiconductors are used for diapazonation.

Keywords: ideal crystal, rare earth elements, compensation, electrical conductivity.
