III-N material grown on a buffer on a silicon substrate includes a single crystal electrically insulating buffer positioned on a silicon substrate. The single crystal buffer includes rare earth aluminum nitride substantially crystal lattice matched to the surface of the silicon substrate, i.e. a lattice co-incidence between REAlN and Si better than a 5:4 ratio. A layer of single crystal III-N material is positioned on the surface of the buffer and substantially crystal lattice matched to the surface of the buffer.

A method of forming a layer of amorphous silicon oxide positioned between a layer of rare earth oxide and a silicon substrate. The method includes providing a crystalline silicon substrate and depositing a layer of rare earth metal on the silicon substrate in an oxygen deficient ambient at a temperature above approximately 500° C. The rare earth metal forms a layer of rare earth silicide on the substrate. A first layer of rare earth oxide is deposited on the layer of rare earth silicide with a structure and lattice constant substantially similar to the substrate. The structure is annealed in an oxygen ambience to transform the layer of rare earth silicide to a layer of amorphous silicon and an intermediate layer of rare earth oxide between the substrate and the first layer of rare earth oxide.
