Glass-forming tendency, physiocochemical properties and rigidity percolation of the Ge-Se-Fe system

The glass-forming region in the chalcogenide Ge-Se-Fe system has been determined. Properties such as the glass transition temperature, density, molar volume, and microhardness have been studied. The extrema in the property-composition dependence at average co-ordination number Z = 2.4 is attributed...

More Information
Summary:The glass-forming region in the chalcogenide Ge-Se-Fe system has been determined. Properties such as the glass transition temperature, density, molar volume, and microhardness have been studied. The extrema in the property-composition dependence at average co-ordination number Z = 2.4 is attributed to the network transition from a floppy to a rigid type.
