A nitride semiconductor structure and a semiconductor light emitting device including the same are revealed. The nitride semiconductor structure includes a light emitting layer disposed between a n-type semiconductor layer and a p-type semiconductor layer, and a hole supply layer disposed between the light emitting layer and the p-type semiconductor layer. The hole supply layer is made from material InxGa1-xN (0<x<1) and is doped with a Group IV-A element at a concentration ranging from 1017 to 10 cm−3. By being doped with the Group IV-A element, the concentration of holes is increased and inactivation caused by Mg—H bonds is reduced. Thus Mg is activated as acceptors and the light emitting efficiency is further increased. |
