Abstract

The time dependent photocurrent of $Al_2_0 As_x Te_8_0 - x$ glasses has been studied at low temperatures. It is found that the photocurrent of all the $Al_2_0 As_x Te_8_0 - x$ samples studied does not decrease appreciably during illumination, which is consistent with the behavior of other narrow band gap amorphous chalcogenides. Further, the photosensitivity is found to be maximized for the composition x=25, which can be associated with rigidity percolation.
