    摘要: A single crystal germanium-on-silicon structure includes a single crystal silicon substrate. A single crystal layer of gadolinium oxide is epitaxially grown on the substrate. The gadolinium oxide has a cubic crystal structure and a lattice spacing approximately equal to the lattice spacing or a multiple of the single crystal silicon. A single crystal layer of lanthanum oxide is epitaxially grown on the gadolinium oxide with a thickness of approximately 12 nm or less. The lanthanum oxide has a lattice spacing approximately equal to the lattice spacing or a multiple of single crystal germanium and a cubic crystal structure approximately similar to the cubic crystal structure of the gadolinium oxide. A single crystal layer of germanium with a (111) crystal orientation is epitaxially grown on the layer of lanthanum oxide.

    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.
