简介 A rare earth oxide gate dielectric on III-N material grown on a silicon substrate includes a single crystal stress compensating template positioned on a silicon substrate. The stress compensating template is substantially crystal lattice matched to the surface of the silicon substrate. A GaN structure is positioned on the surface of the stress compensating template and substantially crystal lattice matched thereto. An active layer of single crystal III-N material is grown on the GaN structure and substantially crystal lattice matched thereto. A single crystal rare earth oxide dielectric layer is grown on the active layer of III-N material.
