    • There is provided a semiconductor light emitting device including: first and second conductivity type semiconductor layers; and an active layer disposed between the first and second conductivity type semiconductor layers and having a structure in which a plurality of quantum barrier layers and a plurality of quantum well layers are alternately disposed, wherein at least one of the plurality of quantum well layers includes a first region in which band gap energy is reduced through a first slope and a second region in which band gap energy is reduced through a second slope different from the first slope. The influence of polarization is minimized by adjusting the shape of the band gap of the quantum well layer, crystallinity and internal quantum efficiency can be enhanced.
    • 提供一种半导体发光器件,包括:第一和第二导电类型半导体层; 以及设置在第一和第二导电类型半导体层之间并且具有多个量子势垒层和多个量子阱层交替设置的结构的有源层,其中多个量子阱层中的至少一个包括 带隙能量通过第一斜率​​减小的第一区域和通过不同于第一斜率的第二斜率使带隙能量减小的第二区域。 通过调整量子阱层的带隙的形状,极化的影响被最小化,可以提高结晶度和内部量子效率。
