    摘要: A substrate comprising a trench lateral epitaxial overgrowth structure including a trench cavity, wherein the trench cavity includes a growth-blocking layer or patterned material supportive of a coalescent Pendeo layer thereon, on at least a portion of an inside surface of the trench. Such substrate is suitable for carrying out lateral epitaxial overgrowth to form a bridged lateral overgrowth formation overlying the trench cavity. The bridged lateral overgrowth formation provides a substrate surface on which epitaxial layers can be grown in the fabrication of microelectronic devices such as laser diodes, high electron mobility transistors, ultraviolet light emitting diodes, and other devices in which low dislocation density is critical. The epitaxial substrate structures of the invention can be formed without the necessity for deep trenches, such as are required in conventional Pendeo epitaxial overgrowth structures.

    摘要: A laser diode and method for fabricating same, wherein the laser diode generally comprises an InGaN compliance layer on a GaN n-type contact layer and an AlGaN/GaN n-type strained super lattice (SLS) on the compliance layer. An n-type GaN separate confinement heterostructure (SCH) is on said n-type SLS and an InGaN multiple quantum well (MQW) active region is on the n-type SCH. A GaN p-type SCH on the MQW active region, an AlGaN/GaN p-type SLS is on the p-type SCH, and a p-type GaN contact layer is on the p-type SLS. The compliance layer has an In percentage that reduces strain between the n-type contact layer and the n-type SLS compared to a laser diode without the compliance layer. Accordingly, the n-type SLS can be grown with an increased Al percentage to increase the index of refraction. This along with other features allows for reduced threshold current and voltage operation.

    摘要: A light emitting device with a coupled quantum well structure in an active region. The coupled quantum well structure may include two or more wells are separated by one or more mini-barriers, and the wells and mini-barriers together are sandwiched by barriers. The coupled quantum well structure provides almost the same effect as a wide quantum well, due to the coupling of the wavefunctions through the mini-barrier. The light emitting device may be a nonpolar, semipolar or polar (Al,Ga,In)N based light emitting device.
