Effect of lithium ion irradiation on the glass transition kinetics of Se98In2 chalcogenide glass

Abstract

Glass transition kinetics in glassy Se98In2 alloy is studied using differential scanning calorimetry under two different conditions. In the first condition, normal samples of the present glass are used. In the second condition, the ion-irradiated samples are used to see the effect of ionic irradiation on the glass transition kinetics of present alloy. For this high energetic beam (50 MeV) of lithium ions is used. After the ion irradiation on the glass, drastic changes in kinetic parameters of glass transition are observed. The results are explained by the model developed by Kastner et al. (Valence-alternation model for localized gap states in lone-pair semiconductors, Phys. Rev. Lett. 37 (1976), pp. 1504-1507).
