Photoconductivity of the Amorphous As2Se3 Film in the Medium Infrared Range

The photocurrent spectra and transient current-voltage characteristics for amorphous As₂Se₃ film sandwiched between two aluminum electrodes are presented. During the measurements, the sample was illuminated with the light from the spectral range 0.8 to 4 mum. The origin of photoresponse related to the involvement in the process of the deep defect centers is discussed
