Název v původním jazyce

Study of Structural Relaxation of Ge-Se and Ge-S Chalcogenide Glasses

Popis výsledku v původním jazyce

The structural relaxation of chalcogenide glasses related to the viscosity behaviour of their undercooled liquids was studied. The volume and enthalpy relaxation of GeySe100-y (y =0,8 and 10) and GeyS100-y (y = 38 and 40) glasses was studied by using length dilatometry, mercury dilatometry and calorimetry. Both volume and enthalpy relaxation were studied under isothermal and non-isothermal conditions. It was found that the equilibrium time scale of relaxation experiments are practically same for both volume and enthalpy relaxation. Relaxation behaviour of studied chalcogenide glasses was described by Tool-Narayanaswamy-Moynihan model and the parameters of this model (effective activation energy, parameter of non­exponentiality, parameter of nonlinearity x and pre­exponencial factor A) were determined. The volume and enthalpy relaxation can be sufficiently well predicted by using the same set of TNM parameters. The effective activation energy of TNM model is close to the activation ener
