Jr. King et al., MATHEMATICAL-MODELING OF THE INTERSTITIALCY DIFFUSION MECHANISM, Proceedings - Royal Society. Mathematical and physical sciences, 450(1940), 1995, pp. 623-649
We consider the diffusion of an impurity through a semiconductor by an
interstitialcy mechanism. The model is initially formulated as a syst
em of differential-difference equations which account for the discrete
nature of the crystal lattice. The corresponding continuum limit is d
erived and some numerical and asymptotic results are presented.
