    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: This invention relates to structures and fabricating methods of light-emitting diodes capable of emitting white or a color within full-visible-spectrum with better efficiency and flexibility. An embodiment provides a light-emitting diode array consisted of one or more light-emitting diodes on a substrate. Each light-emitting diode comprises a first doped nanorod, an active light-emitting region consisted of one or more nanodisks on the first doped nanorod, and a second doped nanorod on the active light-emitting region. Another embodiment provides a fabricating method of the light-emitting diode array.
