Paper Abstract

The paper presents the derivation of expression enabling the determination of the concentration level of dopands introduced in the solid state materials by thermodiffusion (grad T > O). It enables us to estimate the possibilities of exceeding the limit of solubility achieved during the diffusion processes (grad T equals O). The analysis of the effect is given as well as its significance in modification of physico-chemical properties of substances in the solid state. The definition of thermodiffusive drift of the mass is introduced, as a consequence of action and changes resulting from temperature gradient. The expressions enabling calculation of drift quantity of migrating mass are given. It is the relation between the solubility level and the factors influencing the character and drifting mass intensity.
