Effect of SHI irradiation on Se-Te-Sn thin films
- 1. Jamia Millia Islamia, Dept. of Physics, New Delhi (India)
Description
We have study the effect of Tin impurity and Swift heavy ion irradiation (SHI) on the optical properties of chalcogenide thin films. Thin films are prepared by thermal evaporation technique and irradiated by swift heavy ion beam of 60 MeV Si5+ ion with fluence of 5*1012 ions/cm2. The SHI has induced structural and optical changes in the thin films due to which optical band gap has decreased. The reduction of the optical band gap may be due to the increase of the defect states near to the band tails in the band gap during irradiation. (authors)
