GaN-on-diamond technology platform: Bonding-free membrane manufacturing process
AIP Advances, 2020 GaN-on-diamond samples were demonstrated using a membrane-based technology. This was achieved by selective area Si substrate removal of areas of up to 1 cm × 1 cm from a GaN-on-Si wafer, followed by direct growth of a polycrystalline diamond using ...
