Description
Summary:The limiting displacement of an atom (a group of atoms), which corresponds to the maximum of the interatomic interaction force, is treated as a process of atomic excitation in liquids and glasses. The formation, migration, and disappearance of excited atoms are caused by local fluctuations of the configurational entropy. These processes in chalcogenide (and other) glasses are considered small-scale low-energy processes. The parameters of the excited state model as applied to oxygen-free inorganic systems are analyzed.[PUBLICATION ABSTRACT]
