Microhardness and elastic properties of bulk glasses and thin films of the Ge/sub x/-Sb/sub 40-x/-S/sub 60/ family

The microhardnesses (H) of bulk glasses and thin films in the Gex-Sb/sub 40-x/S/sub 60/ family has been measured. The volume of the micro-voids (V/sub h/), their formation energy (E/sub h/) and the module of elasticity (E) have been calculated. It is assumed that the bulk glasses and thin films have different elasticity levels due to the deformation of specific chemical bonds.
