Semi-Insulating GaN Template on Sapphire (0001),3"x 0.5mm,1sp GaN Film:5um

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.
