Self-Organized Structures And Nanosized Levels Of Their Formation In The Non-Crystalline Materials As(Ge)-S(Se) System Induced By White Noise

Abstract

Complex researches of the processes of self-organization and the formation of self-organized structures by the presence of white noise in the non-crystalline materials As (Ge)-S (Se) systems have been carried out, the results of which get the following conclusions: - Investigation of the influence of cooling velocity fluctuations in the approach of white noise on the formation of self-organized structures of non-crystalline materials makes it possible to determine the threshold values of the intensity noise at which the structural characteristics of non-crystalline materials are insensitive to changing conditions of their obtaining. To predict also the formation of self-organized structures at noise determined by the noise intensities . - From the nature of the distribution function of the relative change in the temperature of the loss of dynamic stability, it was found that the transition in the non-crystalline state can be implemented, maintaining a constant cooling velocity, but increasing the intensity of the fluctuations of the external temperature field more than the threshold value . - The presence of transition induced by noise is also established, which is related to the displacement of the deterministic bifurcation diagram. Qualitative change in the behavior of the system, which is described by the distribution function , is observed at intensities greater than the threshold value, and the state of the system is determined by the number and position of extremums of probability density .
