    摘要: In some embodiments of the invention, a device includes a first semiconductor layer, a second semiconductor layer, a third semiconductor layer, and a semiconductor structure comprising a III-nitride light emitting layer disposed between an n-type region and a p-type region. The second semiconductor layer is disposed between the first semiconductor layer and the third semiconductor layer. The third semiconductor layer is disposed between the second semiconductor layer and the light emitting layer. A difference between the in-plane lattice constant of the first semiconductor layer and the bulk lattice constant of the third semiconductor layer is no more than 1%. A difference between the in-plane lattice constant of the first semiconductor layer and the bulk lattice constant of the second semiconductor layer is at least 1%. The third semiconductor layer is at least partially relaxed.

    摘要: A method of forming a semiconductor structure including providing a single crystal semiconductor substrate of GaP, and fabricating a graded composition buffer including a plurality of epitaxial semiconductor Inx(AlyGa1−y)1−xP alloy layers. The buffer includes a first alloy layer immediately contacting the substrate having a lattice constant that is nearly identical to that of the substrate, subsequent alloy layers having lattice constants that differ from adjacent layers by less than 1%, and a final alloy layer having a lattice constant that is substantially different from the substrate. The growth temperature of the final alloy layer is at least 20° C. less than the growth temperature of the first alloy layer.
