Abstract

Results on the reversibility of the light-induced saturation and dark- and light-annealing of the deep-level defects in a-S:H films are presented. The value of the saturated defect density (Nsat) in three samples obtained after initial light-soaking was observed to decrease upon cyclic light-annealing and saturation. This drop in Nsat was observed in two samples after the second illumination while in another sample the drop was observed only after a series of experiments carried out to determine the temperature dependence of Nsat
