Relative influence of topology, dimensionality and stoichiometry towards the properties of covalent network glasses
- 1University of Arizona, United States
Trends in density and fragility are analyzed in the Ge-As-Se, As-Se and Ge-Se system for the purpose of identifying correlation with structural characteristics related to topology, stoichiometry and dimensionality. The Ge-As-Se system provides the most revealing testbed as it permits to isolate individual effects. The fragility of Ge-As-Se glasses is clearly controlled by stoichiometric factors while the topological transition at
