Gallium Nitride Epitaxial wafer on sapphire substrate supplier china

GaN technology today is important technology player- Gallium Nitride on Silicon Carbide (GaN on SiC), Gallium Nitride on Silicon (GaN on Si) and Gallium Nitride on Sapphire (GaN on Sapphire). They are used in LED, RF and microwave devices. We can see a dilemma in the GaN supply chain compared with GaAs and its life cycle. Cost-sensitive applications will still go the path of GaAs technology.  At the same time, foundries and researchers will service diverse, low-volume applications with specialty GaN processes. GaN on SiC will remain focusing on low-volume, niche applications because of higher cost of substrate material,while GaN on Si has lower efficiency though it has low cost of substrate.
