Abstract: The effect of γ-irradiation with a dose of Dγ = 100 krad on the parameters of states localized in the forbidden band in n-In0.999Er0.001Se and n-In0.997Er0.003Se single crystals in the temperature range of 100–300 K was studied. It was found that γ-radiation exposure alters the characteristics of states localized near the Fermi level: a decrease in their density and concentration of deep traps responsible for hopping conductivity, an increase in their energy dispersion and average hopping distance. The radiation-induced defect concentrations in the InSe systems were quantitatively determined. [ABSTRACT FROM AUTHOR]
