Rezumat

From long-term (20 to 1000 s) photocapacitance relaxation measurements on an Al-As2Se3 junction the spectral dependence of density and photoionization cross section of the gap states was derived in the range from 1.35 to 1.92 eV. Two photoionization thresholds at 1.36 and 1.53 eV have been found and ascribed to the gap states of charged defects.
