Abstract

The inherent optical anisotropy and relaxation structure evolution in fresh As-S(Se) amorphous films have been interpreted as the results of self-organized nanonetworks of non crystalline solids. To explain the appearance and characteristic features of the intrinsic anisotropy a phenomenological model based on the structural and chemical peculiarities (distinct structural sites) of as-evaporated amorphous films has been suggested. Conventional photo-induced anisotropy has also been considered. The role of As4S(Se)4 structural units relating to the appearance of optical anisotropies in the films which possess the properties of dissipative structures is being discussed..
