Gallium nitride is a kind of binary III/V direct band gap semiconductor, which is very suitable for high power transistors which can work at high temperature.
Nano silica is a kind of inorganic chemical material. It is amorphous white powder, non-toxic, tasteless, pollution-free, spherical microstructure, flocculent, and reticulate quasi-granular structure.
Nano silica has many properties that conventional materials do not have. The particle size distribution of nano silica is very narrow, most of which are within 100 nm, with many micropores and large specific surface area.
