In this work, the strategy for numerical solutions in transport processes is investigated. Permeation problems can be solved analytically or numerically by means of Finite Difference Method (FDM), while choosing Euler forward explicit backwards implicit formalism. The first method easiest and most commonly used, not yet well established needs further development. Hereafter, a possible solution ...

An analytical solution of the equation describing diffusion of intrinsic point defects in semiconductor crystals has been obtained for a one-dimensional finite-length domain with the Robin-type boundary conditions. The distributions of point defects for different migration lengths of defects have been calculated. The exact analytical solution was used to verify the approximate numerical solutio...
