  • Patent number: 9685586
    Abstract: A nitride semiconductor structure and a semiconductor light emitting device including the same are revealed. The nitride semiconductor structure mainly includes a stress control layer disposed between a light emitting layer and a p-type carrier blocking layer. The p-type carrier blocking layer is made from AlxGa1-xN (0<x<1) while the stress control layer is made from AlxInyGa1-x-yN (0<x<1, 0<y<1, 0<x+y<1). The light emitting layer has a multiple quantum well structure formed by a plurality of well layers and barrier layers stacked alternately. There is one well layer disposed between the two barrier layers. Thereby the stress control layer not only improves crystal quality degradation caused by lattice mismatch between the p-type carrier blocking layer and the light emitting layer but also reduces effects of compressive stress on the well layer caused by material differences.
