Analysis of random events in physical and chemical processes flowing in materials of semiconductor products under external influences and thermal aging

Abstract

Abstract. It has been proposed to consider physical and chemical processes in materials of semiconductor products under external influences and thermal aging as flows of the random events. The mathematical analysis of random events in the physical and chemical processes has been presented. The theoretical results have been applied to the analysis of a number of processes. Keywords

Physical mechanisms and models of long-term transformations of radiative recombination in n-GaAs due to the magnetic field treatments

“…If the movement of defects is diffusive, in accordance with [14], [15,16]. The latter circumstance may indicate some generality of non-thermal mechanisms of interaction of submicrometer waves and weak magnetic fields with semiconductor structures.…”

“…To solve the first problem, we use the results of the work [14], which shows that the physical processes are caused by random events, and the corresponding random variables -the times before the events -obey the distribution Weibull-Gnedenko.…”

“…Being based on [14], we use Weibull-Gnedenko distribution as F 1 (t) and F 2 (t). Then, in a general case F 1 (t) and F 2 (t) can be expressed as follows [14]:…”

Probabilistic approach to the analysis of regularities in behavior of material parameters of electronic equipment under action of external fields

“…As it was noted in [1], the effects of electric, magnetic, electromagnetic and radiation fields on materials of semiconductor products lead to changes in states of ensembles of particles and defects. Behavior of these ensembles is caused by flow of random events in physical and chemical processes.…”

“…By analogy with [1], where the term of event intensity is used, we can write an expression for the sensitivity of events:…”
