Abstract:
A nitride semiconductor structure and a semiconductor light emitting device including the same are revealed. The nitride semiconductor structure includes a multiple quantum well structure formed by a plurality of well layers and barrier layers stacked alternately. One well layer is disposed between every two barrier layers. The barrier layer is made of A x In y Ga 1−x−y N (0<x<1, 0<y<1, 0<x+y<1) while the well layer is made of In z Ga 1−z N (0<z<1). Thereby quaternary composition is adjusted for lattice match between the barrier layers and the well layers. Thus crystal defect caused by lattice mismatch is improved.

Claim (Index 6):
A nitride semiconductor structure comprising:\n a first type doped semiconductor layer; a second type doped semiconductor layer; a light emitting layer disposed between the second type doped semiconductor layer and the first type doped semiconductor layer, the light emitting layer comprising a multiple quantum well (MQW) structure, wherein the MQW structure comprises a plurality of barrier layers and a plurality of well layers stacked alternately; an InGaN based second type hole supply layer disposed between the second type doped semiconductor layer and the light emitting layer; an AlGaN based first type carrier blocking layer disposed between the first type doped semiconductor layer and the light emitting layer; and an AlGaN based second type carrier blocking layer disposed between the second type doped semiconductor layer and the InGaN based second type hole supply layer, wherein the InGaN based second type hole supply layer is doped with a second type dopant at a concentration larger than 10 18  cm \u22123  and carbon at a concentration between 10 17  cm \u22123  and 10 20  cm \u22123 .
