| 摘要 |
A semiconductor light-emitting device includes a substrate, a first doped semiconductor layer, a second doped semiconductor layer situated above the first doped semiconductor layer, and a multi-quantum-well (MQW) active layer situated between the first and the second doped layers. The device also includes a first electrode coupled to the first doped semiconductor layer, wherein part of the first doped semiconductor layer is passivated, and wherein the passivated portion of the first doped semiconductor layer substantially insulates the first electrode from the edges of the first doped semiconductor layer, thereby reducing surface recombination. The device further includes a second electrode coupled to the second doped semiconductor layer and a passivation layer which substantially covers the sidewalls of the first and second doped semiconductor layers, the MQW active layer, and part of the horizontal surface of the second doped semiconductor layer which is not covered by the second electrode.
