Summary

Modern technologies of the sold-state diffusion, the ion exchange and the ion implantation allow significantly increase the impurity concentration within material surface layers, making it possible to introduce various impurities (or their combinations) into different regions of the sample surface [6 - 8]. The approach of surface doping makes possible varying the physical properties of material surface layer within its different areas over a wide range
