Abstract
Amorphous selenium containing different concentrations of sulphur (0-5 at.%) has been prepared by quenching the melt in air. The compositional dependence of density, hardness, specific heat, glass forming tendency as well as crystallization enthalpy have been measured, and the correlation between the obtained data and the chemical binding has been discussed. A cyclic scanning technique has been used to investigate the thermally induced phase during two consecutive heating-cooling cycles covering the temperature range Tg-Tm. The activation energy of crystallization using non-isothermal technique (DSC) has been determined and discussed.
