Abstract:
1. A high fill factor textured light emitting diode structure comprising: a first textured cladding and contact layer comprising a doped III-V or II-VI group compound semiconductor or alloys of such semiconductors deposited by epitaxial lateral overgrowth (ELOG) onto a substrate patterned with a plurality of regions from which said overgrowth is initiated such that said first textured cladding and said contact layer are continuous over said substrate; a textured undoped or doped active layer comprising a III-V or II-VI group semiconductor or alloys of such semiconductors and where radiative recombination of electrons and holes occurs or intersubband transition occurs, the active layer being continuous over said first textured cladding and contact layer; and a second textured cladding and contact layer comprising a doped III-V or II-VI group semiconductor or alloys of such semiconductors.
