Kinetics of First Order Phase Transformation in Se75Te19In6 Glass for Phase Change Memory

In the present research work, we have studied the kinetics of first order phase transformation in Se75Te19In6 glass synthesized by melt quenching technique. The amorphous nature of the synthesized sample was confirmed by High Resolution X-Ray Diffraction (HRXRD). The kinetics study during phase transformation were studied by Differential Scanning Calorimetry (DSC) under non-isothermal conditions at various heating rates 5, 10, 15, 20 and 25K/min. The values of kinetics parameters such as glass transition (Tg), on-set crystallization (Tc), peak crystallization (Tp) and melting temperature (Tm) were determined with the help of DSC thermograms. The activation energies of crystallization (ΔEc) and structural relaxation (ΔEt) were calculated by using Kissinger, Ozawa and Moynihan approaches and found to be in good agreement to each other.
