Paper Title
Effect of Partial Substitution of Sb on Thermophysical Properties of Se based Chalcogenide Glasses

Abstract
Thermophysical properties of glassy Ge-Sn-Se-Sb quaternary chalcogenide system has been investigated in this research paper. Calorimetric parameters viz. glass transition temperature Tg, crystallization temperature Tc, Hruby parameter etc. has been evaluated using differential scanning calorimetric technique under non isothermal conditions at the constant heating rate of 100C. Variations of physical parameters viz. average coordination number , number of constraints N, number of floppy modes f etc. have also been calculated to understand the glass forming ability of samples. Variations in Tg has been supported by chemically ordered network model. Higher difference between crystallization temperature and glass transition temperature in DSC traces proves that samples under investigation have good thermal stability.
