Modelling of the Structure and Structural Transformations in Amorphous Chalcogenides

Abstract

Computer relaxed structural models of arsenic based chalcogenide glasses allowed to demonstrate that the atomic configurations in these materials are anisotropic with a strong tendency to extend as disordered layers. In the frame of these models the photostructural transformations and photoinduced anisotropy find a straightforward explanation.
