英文摘要 | A Group III-V nitride compound semiconductor light emitting device is constructed without the employing homogeneous layers of AlGaN. Instead of homogeneous AlGaN cladding layers, GaN cladding layers are utilized. Since high temperature growths that accompany the formation of AlGaN layers is no longer required, the stochiometric amount of indium in InxGa1-xN core layers utilized in the active region may be made greater to achieve better electrical and optical properties in the device. The loss of waveguiding achieved by the higher refractive index layers of AlGaN is compensated by the use of core layers of InGaN on adjacent sides of the active region comprising InyGa1-yN layer or layers. Other techniques are disclosed utilizing digital alloying of cladding layers comprising GaN/AlN superlattices or AlxGa1-xN/AlyGa1-yN superlattices, or growing Group III-V nitride devices on selected regions of the growth surface of the substrates so that large stresses are not produced as would be the case with uniform growth over the entire growth surface of the substrate. |
