Description

It is presented the dependence of the photoconductivity spectra in the irradiated by neutrons with fluence 1e14 - 1e16 cm-2. The deep local levels are identified by Lucovsky model, data about traps obtained from thermally stimulated conductivity and the effects of conductivity via impurity (traps) band - from the temperature dependence of persistant conductivity. The results are discussed involving the lifetime, mobility of carriers and induced inhomogeneities dependence on the fluence models.
