GaN Template on Sapphire (0001), N type, undoped, 2"x 0.5mm,1sp GaN Film:30um, (Production Grade) - FmGaNonALC50D05C1FT30um

-GaN Template on saphhire is made by a hydride vapor phase epitaxy (HVPE)-based method. During the HVPE process, HCl reacts with molten Ga to form GaCl, which in turn reacts with NH3 to form GaN.  GaN template is a cost effective way to replace GaN single crystal substrate.
