Role of Silver Incorporation on the Specific Heat in Glassy Se<sub>80</sub>Te<sub>20</sub> Alloy

Abstract

Specific heat measurements have been made in glassy Se 80−x Te 20 Ag x (0 ≤ x ≤ 15) alloys using differential scanning calorimetry (DSC) technique. An extremely large increase in the specific heat values has been observed at the glass transition temperature. It has also been found 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. This indicates that the incorporation of Ag in binary Se 80 Te 20 alloy in the present study influences the structure of the binary alloy. Specific heat of the additive element Ag is found to be important for the observed changes in the specific heat of the ternary alloys as compared to binary alloy.
