    摘要： A light emitting device includes a p-type semiconductor layer, an n-type semiconductor layer, and an active region between the n-type semiconductor layer and the p-type semiconductor layer. A non-transparent feature, such as a wire bond pad, is on the p-type semiconductor layer or on the n-type semiconductor layer opposite the p-type semiconductor layer, and a reduced conductivity region is in the p-type semiconductor layer or the n-type semiconductor layer and is aligned with the non-transparent feature. The reduced conductivity region may extend from a surface of the p-type semiconductor layer opposite the n-type semiconductor layer towards the active region and/or from a surface of the n-type semiconductor layer opposite the p-type semiconductor layer towards the active region.

    摘要： Light emitting devices include a gallium nitride-based epitaxial structure that includes an active light emitting region and a gallium nitride-based outer layer, for example gallium nitride. A indium nitride-based layer, such as indium gallium nitride, is provided directly on the outer layer. A reflective metal layer or a transparent conductive oxide layer is provided directly on the indium gallium nitride layer opposite the outer layer. The indium gallium nitride layer forms a direct ohmic contact with the outer layer. An ohmic metal layer need not be used. Related fabrication methods are also disclosed.

    摘要： Light emitting devices include an active region comprising a plurality of layers and a pit opening region on which the active region is disposed. The pit opening region is configured to expand a size of openings of a plurality of pits to a size sufficient for the plurality of layers of the active region to extend into the pits. In some embodiments, the active region comprises a plurality of quantum wells. The pit opening region may comprise a superlattice structure. The pits may surround their corresponding dislocations and the plurality of layers may extend to the respective dislocations. At least one of the pits of the plurality of pits may originate in a layer disposed between the pit opening layer and a substrate on which the pit opening layer is provided. The active region may be a Group III nitride based active region. Methods of fabricating such devices are also provided.
