Synergetrics elements in physical processes in p-n-transition

Abstract

The present stage of development of science is characterized by rapid growth of scientific information. At the same time strengthening of integration processes of various sections of fundamental science is observed. One of the most important scientific achievements of the last time can consider understanding of a role of unstable, critical conditions in matter evolution. Today the accent is transferred from studying of equilibrium conditions of system to a research of conditions of instability, mechanisms of emergence new, the births and reorganizations of structures, self-organization. Thus, it is possible to speak about formation of a new scientific paradigm. Self-organization is followed by processes of emergence of macroscopic ordered existential structures in difficult nonlinear systems. At the same time the last have to be in the states far from balance near bifurcation points in the neighborhood of which the behavior of system becomes unstable. Emergence of such structures is possible in thermodynamic opened, i.e. exchanging substance or energy with the environment, systems which are described by the nonlinear dynamic equations. Besides, the deviation of such systems from equilibrium state has to exceed some critical value. The semiconductor device and the external power supply make a peculiar thermodynamic system which can also be in a nonequilibrium state. It is natural that in such system there have to be self-organized processes. In general work of the majority of semiconductor devices is based on the self-organized processes arising in such systems. Therefore, studying of processes of selforganization in semiconductor devices is an important task. In work mechanisms emergence, processes of self-organization in one of the major objects, so-called p-n of transition are described.
