Description
Crystallization kinetics is studied in glassy Ge22Se78-xBix(0≤x≤10) using isothermal annealing at various temperatures between the glass transition and melting. D.c. conductivity is taken as a parameter to estimate the extent of crystallization (α). The activation energy of crystallization (ΔΕ) and the order parameter (n) are calculated by fitting the values of a in Avrami's equations of isothermal transformation. The results indicate that ΔΕ is highly composition dependent and decrease as the Bi concentration increases
