Paring Diffusion Equation

Abstract

In this section, we consider reaction between impurity, point defects, and charges in diffusion phenomenon and diffusion equations for both of impurity and point defects. There are many levels of sophistication of treatment of the interaction of impurity and point defects. We perform approximations step by step, and derive diffusion models in various supplication levels.
