    • نبذة مختصرة :
      The activation energy (E t) of the glass transition process has been obtained for glassy Se80− x Te20M x (M = Ag, Cd, In, Sb) and Se100− x M x (M = In, Te, Sb) systems using differential scanning calorimetry. The composition dependence of E t is explained in terms of fragility index for the systems. A reversal in the trend of the E t is explained using topological models.
