Abstract

Nanoscale mechanical properties of As – S binary chalcogenide glasses for bulk and thin-film samples have been studied, using the nanoindentation technique for a step loading procedure. All components of glass deformation (plastic, elastic. and visco-elastic, or retarded) have been evaluated during the nanoindentation process. An essential redistribution of these components was observed during unloading depending on the composition of the glasses. The same nanoindentation procedure was applied to bulk, as-deposited and annealed thin-film samples of the glasses. Plots of deformation components vs. As concentration (or average covalent coordination number <r>) show a minimum around the As25S75 – As30S70 composition (<r> ≈ 2.30), which corresponds to the rigidity percolation composition, i. e., the transition from the floppy phase to the intermediate one.
