摘要：

In the present report, we have done specific heat measurements in glassy Se80-xTe20Sbx (0 x 15) alloys in glass transition region. Differential scanning calorimetry (DSC) technique is used for this purpose. We have observed a tremendously huge increase in the specific heat (C-p) values at the glass transition temperature. The thermal analysis shows that the values of C-p below glass transition temperature and the difference of C-p values before and after glass transition (C-p) are highly composition-dependent.
