Abstract

In this work, we have reported the specific heat measurements in glassy Se80-xTe20Cdx (0 ≤ x ≤ 15) alloys using differential scanning calorimetry (DSC) technique. A tremendously huge raise in the specific heat (Cp) has been observed at the glass transition temperature. We have also observed that the values of Cp below glass transition temperature and after glass transition are highly composition dependent. This is the sign of that fact that the incorporation of Cd in binary Se80Te20 alloy influences its glassy structure drastically. The observed changes in the specific heat of the ternary alloys as compared to binary alloy are explained in terms of atomic weight of the additive element Cd..
