GaN -Single Crystal Substrate (0001), 50.8mm x 0. 25 mm , N+ type, 2SP

In stock
Item Number: GaN50D025C2NUS5

GaN single crystal substrates 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. The large growth rate enables the growth of self-supporting wafer thicknesses in a convenient time period.
