Rezumat

Measurements are presented for the photocapacitance transient arising at contacts of the metal - amorphous As2Se3 or As 2Se3: Snx (x∼1 at. %) film as response to a pulse of linearly increasing voltage. It was shown, that transient photocapacitance is determined by the deep acceptor-like states, which are quasi-continuously distributed near the Fermi-level. The observed increasing in concentration of deep states in samples with tin impurity was discussed.
