Glass Transition Phenomena, Crystallization Kinetics and Enthalpy Released in Binary Se100-xInx (x = 2, 4 and 10) Semiconducting Glasses

Abstract

Results of Differential Scanning Calorimetry (DSC) under non-isothermal conditions on Se100–xInx (x = 2, 4 and 10) glasses are reported and discussed. The glass transition region has been investigated in terms of activation energy and the dependence of glass transition temperature Tg on coordination number with varying composition and heating rates. The crystallization kinetics and its dimensionality have been studied using two different models viz. Matusita and Ozawa equations. On the basis of the obtained experimental data the temperature difference Tc — Tg and the enthalpy released, ΔHc, are found to be maximum and minimum, respectively, for Se96In4 glass which indicate that this glass is the thermally most stable in the composition range of investigation.
