Crystallization kinetics of amorphous Tex(Bi2Se3)1-x glasses

The activation energy plays a dominant role in deciding the utility of the material for the specific purpose-here storage. The dependence of the peak temperature of crystallization (T-p) on the composition and heating rate (beta) has been studied here. From the heating. rate dependence, T-p, the activation energy for crystallization (E-c) has been evaluated. The activation energy, E-c, calculated using three different approaches is found to decrease with the increase in Bi content. This analysis helps in finding the suitability of an alloy to be used in phase transition optical memories/switches. The results have been analysed using Kissinger's equation for non-isothermal crystallization of materials.
