A further Consideration of the Correlation Factor for Impurity Diffusion in the Diamond Structure

Abstract

The correlation factor for impurity diffusion by single vacancies in the diamond structure is calculated taking into account eight distinct vacancy-atom exchange rates. Arguments are given that such a model is physically more realistic than the usual four frequency model. It turns out that the difference from the results obtained by the latter model can become large. A long range Coulombic impurity-vacancy interaction is also included.
