Crucial effect of glass processing and melt homogenization on the fragility of non-stoichiometric chalcogenides

Sriram Ravindren, K. Gunasekera, Z. Tucker +3

The kinetics of homogenization of binary As $_{x}$ Se $_{100 - x}$ melts in the As concentration range $0%$ $<$ $x$ $<$ $50%$ are followed in FT-Raman profiling experiments, and show th…

Fragility and molar volumes of non-stoichiometric chalcogenides -- the crucial role of melt/glass homogenization

R. Bhageria, K. Gunasekera, P. Boolchand +1

Melt-fragility index (m) and glass molar volumes (Vm) of binary Ge-Se melts/glasses are found to change reproducibly as they are homogenized. Variance of Vm decreases as glasses ho…

Meeting experimental challenges to physics of network glasses: assessing role of sample homogeneity

S. Bhosle, K. Gunasekera, P. Chen +3

We introduce a Raman profiling method to track homogenization of Ge $_{x}$ Se $_{100 - x}$ melts in real time, and show that 2 gram melts reacted at 950°C in high vacuum homogenize in 168…
