The diffusion or migration of atoms in topic, of no matter what shape, is a easy end result of the life of atoms. In metals, atomic diffusion has a good confirmed place of value because it is well-known that there are few metallurgical strategies which don't embrace the diffusion of 1 or extra of the elements. As regards semiconductors any thermal annealing therapy includes atomic diffusion. In semiconductor expertise diffusion strategies supply a necessary and easy technique of fabricating doped buildings. although the significance of diffusion within the preparative procedures of semiconductor constructions and samples, the diffusion established features have bought an empirical outlook verging nearly on alchemy. the 1st try to current a scientific account of semiconductor diffusion tactics was once made by means of Boltaks [11 in 1961. throughout the decade considering that Boltaks' publication seemed a lot paintings germane to figuring out the atomic mechanisms liable for diffusion in semiconductors has been released. the article of the current publication is to provide an account of, and to consolidate, current wisdom of semiconductor diffusion when it comes to simple ideas of atomic migration in crystalline lattices. To this finish, exhaustive compilations of empirical facts were shunned as those can be found somewhere else [2, 31 : awareness has been constrained to contemplating proof in a position to yielding perception into the actual approaches involved in atomic diffusion.

This therefore precludes the use of tracers to follow the chemical diffusion of native defects. The foregoing analysis can be equally well applied to an elemental semiconductor and similar conclusions obtained. Information on D(Ll) can be obtained from the movement of p-n junctions [ 113) and colour boundaries [1141. e. there is no precipitation or association during quenching of the defects being monitored; (ii) no defect species are added to, or removed from, the electro neutrality condition due to the shift in Ep arisinf from the f,j'lench.

3 are the free energy minus the entropy of mixing. 3(a) applies, there will be a free energy gradient due to the gradient in the entropy of mixing term: this gradient constitutes a thermodynamic driving force of magnitude (kTlc) aclax. More generally a thermodyn~mic driving force is any effect which causes the free energy minima (of the diffusant) to vary with position. Lj' The term Lrq Xq describes the flu~ of the rth species due to a temperature gradient VT: the flux created by VT is known as thermal diffusion or, alternatively, as the Soret effect.
