1. Gallium nitride (GaN) is a very hard made material that has a wurtzite crystal structure and probably is the most important semiconductor material as the third generation semi material.
2.  It can be used to emit brilliant light in the form of light emitting diodes (LEDs) and laser diodes, as well as being the key material for next generation high frequency, high power transistors capable of operating at high temperatures.
3. GaN based epitaxial wafer (Sapphire,SiC) Epitaxial wafers are grown by MBE or MOCVD method , one layer or multi-layer structures on Sapphire substrates , diameter up to 4 inch.
