Abstract
Glass science reveals peculiar properties due to the lack of long range order and presence of heterogeneity in Chalcogenide glasses. In thermal studies, structural relaxation at the glass transition region is governed by the activation energy of the cooperative unit (zU). In the cooperative molecular dynamics, we are considering the analysis of three activation energies, namely activation energy per BMS (U), activation energy of the cooperative unit (zU) and the apparent activation energy (z 2 U). From the energetic dynamics of activation energy analysis across the Ge x Se 1- x glass series, data represent three-phase segregation. From our data, we also observed that the value of U CRR /RT g across the Ge x Se 1- x g lass series is nominally changed from 34.343 to 36.19.
