GaN Template ( 500nm) on Silicon Wafer, N type, undoped, 10x10 mm, GaNSi-1010-500-US

In stock
Item Number: GaNSi-1010-500-US

GaN Template on silicon 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 on silicon is a cost effective way to replace GaN single crystal substrate.

  • Nominal GaN thickness:            0.5μm ± 0.1 μm
  • Front Surface finish (Ga-face):    <1nm RMS,  As-grown,
  • Back surface finish:                   Silicon ( 111) N-type P-doped R:0-10
  • GaN orientation:                        C-plane (00.1)
  • Polarity:                                   Ga-face
  • Conduction Type:                      Undoped (N-) and resistivities: < 0.05 Ohm-cm
  • Macro Defect Density:               <1/cm^2
  • Wafer base:                              Silicon [111], 10x10x0.5mm, one side polished
  • There is ~200nm AlN buffer layer between the silicon and GaN
