Calorimetric studies in glassy Se<sub>80−<i>x</i></sub>Te<sub>20</sub>Sb<sub><i>x</i></sub>
TL;DRAbstract
Calorimetric studies have been made in glassy Se80−xTe20Sbx where 0 ≤ x ≤ 15 with a view to calculate the crystallization kinetic parameters. Multi scan technique has been used to calculate the activation energy of crystallization ΔE and the order parameter (n). The results indicate that ΔE is highly composition dependent in these glasses. A discontinuity in ΔE is observed at 10% of Sb which is explained in terms of mechanically optimised structure at a particular average co-ordination number.
