Publication date: Available online 23 June 2017 Source:Journal of Taibah University for Science Author(s): Anjani Kumar, D. Kumar, S.K. Tripathi, R.K. Shukla, A. Kumar The paper reports the role of Ag additives on light induced metastable defects in Se–In glassy alloys using a well-known thermally stimulated current (TSC) technique. Amorphous thin films of Se90In10−xAgx (x=0, 2, 4, 8) were prepared by thermal evaporation. Measurements were made in the given thin films prior to and after exposing amorphous thin films to white light for different exposure times (0–1.5hrs). The density of light induced metastable defects increases with exposure time, and the fractional increase in light induced metastable defect density decreases as Ag concentration increases.
