Abstract

The effect of γ-ray radiation on the electrical properties of heat-treated Tb0.01Sn0.99Se (sample 1) and Tb0.05Sn0.95Se (sample 2) samples is studied. It is found that, as a result of irradiation with γ-ray 1.25-MeV photons, the charge-carrier concentration decreases in the temperature range T = 77−200 K by 17 and 6.3% for samples 1 and 2, respectively. It is assumed that, in the course of irradiation with γ-ray photons, terbium impurity atoms are located between sites of the crystal lattice; in addition, Frenkel defects are formed.
