    摘要： The present disclosure involves an illumination apparatus. The illumination apparatus includes an n-doped semiconductor compound layer, a p-doped semiconductor compound layer spaced apart from the n-doped semiconductor compound layer, and a multiple-quantum-well (MQW) disposed between the first semiconductor compound layer and the second semiconductor compound layer. The MQW includes a plurality of alternating first and second layers. The first layers of the MQW have substantially uniform thicknesses. The second layers have graded thicknesses with respect to distances from the p-doped semiconductor compound layer. A subset of the second layers located most adjacent to the p-doped semiconductor compound layer is doped with a p-type dopant. The doped second layers have graded doping concentration levels that vary with respect to distances from the p-doped semiconductor layer.

    摘要： The present disclosure involves a method of fabricating a semiconductor device. A surface of a silicon wafer is cleaned. A first buffer layer is then epitaxially grown on the silicon wafer. The first buffer layer contains an aluminum nitride (AlN) material. A second buffer layer is then epitaxially grown on the first buffer layer. The second buffer layer includes a plurality of aluminum gallium nitride (AlxGa1−xN) sub-layers. Each of the sub-layers has a respective value for x that is between 0 and 1. A value of x for each sub-layer is a function of its position within the second buffer layer. A first gallium nitride (GaN) layer is epitaxially grown over the second buffer layer. A third buffer layer is then epitaxially grown over the first GaN layer. A second GaN layer is then epitaxially grown over the third buffer layer.
