Analysis of Activation Energies & Experimental Evidence for Energetic Phase Separation in GexSe1-xGlassy System ()
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 (z2U). From the energetic
dynamics of activation energy analysis across the GexSe1-x glass series, data represent three-phase
segregation. From our data, we also observed that the value of UCRR/RTg across the GexSe1-x glass series is nominally changed from 34.343 to 36.19.
