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 AsSe melts in the As concentration range 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…
Superstrong nature of covalently bonded glass-forming liquids at select compositions
K. Gunasekera, S. Bhosle, P. Boolchand +1
Variation of fragility (m) of specially homogenized GexSe100-x melts are established from complex specific heat measurements, and show m(x) has a global minimum at an extremely low…
Melt homogenization and self-organization of chalcogenides glasses: evidence of sharp rigidity, stress and nanoscale phase separation transitions in the GexSe100-x binary
S. Bhosle, K. Gunasekera, P. Boolchand +1
A Raman profiling method is used to monitor growth of GexSe100-x melts and reveals a two step process of homogenization. Resulting homogeneous glasses show the non-reversing enthal…
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 GeSe melts in real time, and show that 2 gram melts reacted at 950°C in high vacuum homogenize in 168…
