Abstract

Differential scanning calorimetry (DSC) was performed at different heating rates under non-isothermal conditions to probe the glass transition kinetics of several Ge-As-Se glasses with different chemical compositions. The change of the glass transition temperature T _g with the heating rate and composition was investigated and the activation energy of the glass transition was estimated. The fragility index was calculated and the correlation to the mean coordination number of Ge-As-Se glasses was discussed.
