Introduction Recent doping processes include diffusion, ion implantation, impurity doping during epitaxy as well as chemical doping methods and fast laser heat-treatment after dopant deposition; all of which are key processes in both materials science and in the fabrication of micro-electronic and nanoelectronic semiconductor devices.
In doing this, we have to confront a complex diffusion system consisting of multi-diffusion species migrating simultaneously into the materials.
This means that diffusion modeling and simulation in nano-sized semiconductor materials will have to be dealt with, and solutions developed.
The very process of diffusion in solids is one of the most complex theoretical problems in solid-state physics and materials science.

InGaAs is direct and narrow bandgap material with ultrahigh electron mobility, and is a promising candidate for optoelectronic device in the near-infrared region.
The designed InGaAs NWs semiconductor device could be radiation hard when compared with other material and its bulk counterpart[9].
With that success of engineering the surface Plasmon polariton by format the dielectric materials and metal within the NWs, this technology could achieve highly efficient photodetector sand dramatically reducing reverse biases with smaller dimension.
