Effect of Sb Content on the Physical Properties of Ge-Se-Te Chalcogenide Glasses

摘要

In the present study, the bulk as-(Se_(80)Te_(20))_(94-x)Ge6Sb_x (x= 0, 1,2,4, 6, 8) glasses were synthesized using melt quenching technique. The physical properties viz coordination number, lone pair of electrons, number of constraints, glass transition temperature, mean bond energy, cohesive energy, electro-negativity and average heat of atomization of the investigated composition are reported and discussed. It is inferred that on increasing Sb content; average coordination number, average number of constraints, mean bond energy, cohesive energy and glass transition temperature increases but lone pair of electrons, average heat of atomization and deviation of stoichiometry decreases.
