“…is successful. The latest study includes number of activated phenomenon such as solid-state diffusion in crystals and polymers, dielectric relaxation and conduction in polymers, thermally stimulated processes in polymers and electronic conduction in amorphous semiconductors [19][20][21][22][23][24][25][29][30][31][32][33][34]. There are also reports of MN rule in kinetic processes, such as amorphous to crystal transition [26,35,36].…”

Glassy alloys of Se 90 In 10-x Ag x were prepared using melt quenching technique. Non-isothermal differential scanning calorimetric (DSC) studies were done on Se 90 In 10-x Ag x (x = 0, 2, 4, 6, 8 at.%) glassy alloys at four different heating rates (β = 5, 10, 15, 20°C/min). Well defined endothermic and exothermic peaks were obtained at glass transition (T g) and crystallization temperature (T c), respectively. Augis and Bennett's method was used to obtain the composition dependent crystallization activation energy (E c) and the pre-exponential factor (η 0) of the Arrhenius expression. A linear dependence between ln η 0 and E c was observed showing the existence of compensation effects of the Meyer-Neldel type. These compensation effects confirm the applicability of Meyer-Neldel (MN) rule for the non-isothermal crystallization in the present case.
