Rezumat

Persistent photoconductivity effects have been studied in amorphous As2Se3 films doped with Sn impurity using both transient and steady-state photocurrent measurements. From the photocurrent spectra the broad distributions of defect states in the band gap of As2Se3:Snx(x>0.5 at.% Sn) samples was evaluated. It was shown that these states contribute significantly to the persistent photoconductivity.
