Effect of Ge and Te on Physical Properties of Cu–Se–In–M (M = Ge, Te) Chalcogenide Glass

Cu5Se75In10M10 (M = Ge, Te) bulk chalcogenide glasses have been prepared by melt quench technique. XRD technique has been used for structural characterization. Absence of peaks confirms the amorphous nature of the studied composites. Some important physical parameters have been investigated theoretically i.e., average coordination number, constraints, density, molar volume, cohesive energy, electro negativity, heat of atomization, bond energy etc. Tichy-Ticha and Lankhorst approach has also been used to study the glass transition temperature Tg. Theoretical analysis of composition shows that there is significant change in the structure of the glass due to rigidity percolation.
