To overcome this problem, heterostructure MOSFET with other semiconducting materials to increase the layer density and carried mobility are required.
However, there are limitation in the choice of materials compatible with Silicon (Si) technology.

Introduction The idea of combining two or more different components to produce new materials with unique properties has been used for many years.
Indeed RH has been used as raw materials for the production of a series of silicon-based materials, including silicon carbide, silica, silicon nitride, reinforced polymer composite, cements and other silicon-based materials [3].
Materials and Methods In selecting raw materials the most important aspect to be taken into account is the purity.
