Description
| - This work is concentrated on the study of structural relaxation of chalcogenide glasses related to the viscosity behaviour of their undercooled liquids. The enthalpy relaxation of pseudobinary glass (GeS2)y(Sb2S3)1-y (y = 0.2 and 0.3) was studied using differential scanning calorimeter. Relaxation behaviour of the studied chalcogenide glasses was described by Tool-Narayanaswamy-Moynihan model and the parameters of this model (effective activation energy Δh*, parameter of nonexponentiality, parameter of nonlinearity and preexponencial factor) were determined. The effective activation energy of TNM model is close to the activation energy of viscous flow of undercooled liquid.

- Tato práce je zaměřena na studium strukturní relaxace chalkogenidových skel a viskozitní chování jejich podchlazených tavenin. Pomocí diferenciální skenovaní kalorimetrie byla studována entalpická relaxace pseudobinárních skel (GeS2)y(Sb2S3)1-y (kde y = 0.2 and 0.3). Relaxační chování těchto skel bylo popsáno Tool-Narayanaswamy-Moynihan modelem a byly určeny parametry tohoto modelu (zdánlivá aktivační energie Δh*, parametr neexponenciality, parametr nelinearity a předexponenciální faktor). Hodnota zdánlivé aktivační energie TNM modelu je blízká hodnotě aktivační energie viskózního toku podchlazené kapaliny. (cs)
