SELF-ORGANIZED STRUCTURES AND FRACTALITY OF THE NON-CRYSTALLINE MATERIALS As (Ge)-S(Se) SYSTEMS

Abstract

In this article research of fractality and processes of structuring non-crystalline materials As (Ge)-S (Se) systems are presented. The peculiarities of structure and properties of non-crystalline solids, their interrelation with methods of obtaining are analyzed. Existing model approaches to describing the structure of non-crystalline solids and the transition to a non-crystalline state consider either individual characteristic time scales of their formation, or a separate group of properties and features of the structure. With significant deviations of the system from equilibrium synergetic effects and the mechanism of transformation of energy and information play a decisive role. The integrity of the formation of a non-crystalline state can be taken into account with the use of a synergetic approach within the framework of the theory of self-organized structures that makes it possible to determine the mode of formation in conjunction with the conditions of obtaining. The dependence of the lifetime and the period of self-organized structures on the cooling velocity are studied. In particular, for non-crystalline materials systems As-S(Se) period Å and correlates with the micro-, nanosized of the middle order. The nature of the bifurcation process of transition to a non-crystalline state in the framework of the theory of neural networks with Hebb and Kohenen algorithms also is revealed.
