Abstract:
A nitride semiconductor light emitting element includes: an n-side layer; a p-side layer; an active layer disposed between the n-side layer and the p-side layer, the active layer comprising: a well layer containing Al, Ga, and N, and a barrier layer containing Al, Ga, and N, wherein an Al content of the barrier layer is higher than an Al content of the well layer; and an electron blocking structure layer between the active layer and the p-side layer, the electron blocking structure comprising: a first electron blocking layer disposed between the p-side layer and the active layer, a second electron blocking layer disposed between the p-side layer and the first electron blocking layer, and an intermediate layer disposed between the first electron blocking layer and the second electron blocking layer.
