    摘要: A method of growing GaN material on a silicon substrate includes providing a single crystal silicon substrate with a (100) surface orientation or a (100) with up to a 10° offset surface orientation and using epi-twist technology, epitaxially growing a single crystal stress managing layer on the silicon substrate. The single crystal stress managing layer includes rare earth oxide with a (110) crystal orientation and a cubic crystal structure. The method further includes epitaxially growing a single crystal buffer layer on the stress managing layer. The single crystal buffer layer includes rare earth oxide with a lattice spacing closer to a lattice spacing of GaN than the rare earth oxide of the stress managing layer. Epitaxially growing a layer of single crystal GaN material on the surface of the buffer, the GaN material having one of a (11-20) crystal orientation and a (0001) crystal orientation.

    摘要: III-N material grown on a silicon substrate includes a single crystal buffer positioned on a silicon substrate. The buffer is substantially crystal lattice matched to the surface of the silicon substrate and includes aluminum oxynitride adjacent the substrate and aluminum nitride adjacent the upper surface. A first layer of III-N material is positioned on the upper surface of the buffer. An inter-layer of aluminum nitride (AlN) is positioned on the first III-N layer and an additional layer of III-N material is positioned on the inter-layer. The inter-layer of aluminum nitride and the additional layer of III-N material are repeated n-times to reduce or engineer strain in a final III-N layer.

    摘要: A method of forming a REO dielectric layer and a layer of a-Si between a III-N layer and a silicon substrate. The method includes depositing single crystal REO on the substrate. The single crystal REO has a lattice constant adjacent the substrate matching the lattice constant of the substrate and a lattice constant matching a selected III-N material adjacent an upper surface. A uniform layer of a-Si is formed on the REO. A second layer of REO is deposited on the layer of a-Si with the temperature required for epitaxial growth crystallizing the layer of a-Si and the crystallized silicon being transformed to amorphous silicon after transferring the lattice constant of the selected III-N material of the first layer of REO to the second layer of REO, and a single crystal layer of the selected III-N material deposited on the second layer of REO.
