Abstract:
1. A method of fabricating a rare earth silicide gate electrode on III-N material grown on a silicon substrate comprising the steps of: providing a single crystal silicon substrate; growing or depositing a single crystal stress compensating template on the silicon substrate, the stress compensating template being substantially crystal lattice matched to the surface of the silicon substrate; growing or depositing a single crystal GaN structure on the surface of the stress compensating template, the GaN structure being substantially crystal lattice matched to the single crystal stress compensating template; growing or depositing an active layer of single crystal III-N material on the GaN structure, the single crystal III-N material being substantially crystal lattice matched to the GaN structure; growing or depositing a single crystal monoclinic rare earth oxide dielectric layer on the active layer of III-N material; and growing or depositing a single crystal rare earth silicide gate electrode on the dielectric layer.
