Özet

The effect of thermal annealing on dark conductivity and thermally stimulated conductivity m ferroelectric-semiconductor TlGaSe2 within the incommensurate phase is investigated. It is shown that both types of conductivities are drastically changed after annealing of the crystal for some hours within the incommensurate phase. The results obtained lead to the conclusion that the main effect of annealing is a large decrease of impurity capture cross sections leading to the dramatic increasing of relaxation times.
