Application of the Excited State Model to Chalcogenide Glasses

摘要

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.
