This study explores the effect of Ag+ ions on transient photoconductivity of thin films of Se75Te20Ag5. The thin films of Se75Te20Ag5 chalcogenide alloys were made by evaporation method using a vacuum chamber at HBTI Kanpur, India. This amorphous system showed the presence of negative photocurrent when white light was stopped showing on the sample. The rise and decay of photoconductivity was ob...
