Enthalpy relaxation of selenium observed by fast scanning calorimetry

The enthalpy relaxation of amorphous selenium was studied using fast scanning calorimeter, where the heating/cooling rates up to 10,000 K s−1 were used. The observed relaxation effects were compared with the measurements done by classical differential scanning calorimetry. Description of the data and prediction of the relaxation behavior using the Tool-Narayanaswamy-Moynihan model is discussed.
