Recently the growing interest in the investigation of the physical properties of chalcogenide glasses stems from the actual and potential technological applications of these materials in solid state devices. The physical parameters viz. average coordination number, number of constraints, cross-linking density, molecular weight, Lone-pair electron, mean bond energy, glass transition temperature etc., with the variation in Germanium content have been studied theoretically in the present article for GexSe80-xTe20 (x = 3, 6, 9, 12, 15, 18 at. %) glassy alloys. Here the well established Tichy-Ticha approach has been used to study the mean bond energy and glass transition temperature.
