Differential scanning calorimetry (DSC) measurements were used to study enthalpic structural relaxation in the TeySe(1−y) glassy system. The examined compositions were y = 0.1, 0.2 and 0.3. Single set of Tool–Narayanaswamy–Moynihan parameters was obtained from the curve-fitting procedure for each studied glass. A comparison with our previous measurements on a-Se was made and the development of particular TNM parameters with increasing Te content was discussed in terms of changes in molecular structure of the material. The curve-fitting results were further verified by several independent non-fitting methods.
Research Highlights►Enthalpic structural relaxation in TeySe(1−y) glassy system was studied by DSC. ►Single set of TNM parameters was obtained for each studied composition. ►Non-fitting methods of TNM parameters estimation confirm curve-fitting results. ►Relaxation dynamics on molecular scale was discussed on the basis of TNM parameters.
