Amorphous-to-crystalline transition in Te-doped Ge2Sb2Se5 glass
Original language description
Differential scanning calorimetry (DSC) was used to study crystallization in Ge2Sb2Se4.5Te0.5 glass under non-isothermal conditions. The crystallization kinetics was described in terms of the autocatalytic estak-Berggren model. An extensive discussion ofall aspects of a full-scale kinetic study for a crystallization process was undertaken. In particular, the effect of Te a dagger" Se substitution on the complexity of the crystallization process was analyzed. The addition of tellurium enhances bulk crystallization originating from volume nuclei at the expense of the surface/defects-based crystallization mechanism. Significantly higher activation energy in the case of the Te-doped material was attributed to the larger mass of the combined Se-Te chains and the larger spatial restrictions for their movement. On the other hand, the slightly lower crystallization temperature of the Te-doped glass corresponds to its higher tendency for crystallization. A supplemental X-ray diffraction study
