发光器件
摘要：
提供了一种发光器件，其包括：（a）通过在底部衬底上顺序地生长第一导电类型的第一化合物半导体层、由化合物半导体形成的活性层、以及第二导电类型的第二化合物半导体层来获得的层结构；（b）形成于第二化合物半导体层上的第二电极；以及（c）电连接于第一化合物半导体层的第一电极。该层结构由第二化合物半导体层的在第二化合物半导体层的厚度方向上的至少一部分形成。第一化合物半导体层具有大于0.6μm的厚度。第一化合物半导体层中形成有高折射率层，该高折射率层由具有比第一化合物半导体层的化合物半导体材料的折射率高的折射率的化合物半导体材料形成。
摘要（英）：

Provided is a light-emitting device including (a) a layer structure obtained by sequentially growing on a base substrate a first compound semiconductor layer of a first conductivity type, (b) an active layer formed of a compound semiconductor, and (c) a second compound semiconductor layer of a second conductivity type; a second electrode formed on the second compound semiconductor layer; and a first electrode electrically connected to the first compound semiconductor layer. The layer structure formed of at least a part of the second compound semiconductor layer in a thickness direction of the second compound semiconductor layer. The first compound semiconductor layer has a thickness greater than 0.6 [mu]m. A high-refractive index layer formed of a compound semiconductor material having a refractive index higher than a refractive index of a compound semiconductor material of the first compound semiconductor layer is formed in the first compound semiconductor layer.
