GaN Template on Sapphire(0001) 2"x 0.5mm,1sp ,GaN Film: 20um ,Semi-insulated--Research Grade

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.
