Abstract:
1. A semiconductor light emitting device comprising: a first super lattice layer including pairs of at least two semiconductor layers which have compositions different from each other, wherein the pairs of the at least two semiconductor layers are a periodic repeating of the at least two semiconductor layers; a first conductive semiconductor layer on the first super lattice layer; an active layer on the first conductive semiconductor layer, wherein the active layer includes a single quantum well structure or a multi-quantum well structure having a quantum barrier layer and a quantum well layer on the quantum barrier layer; a conductive super lattice layer on the active layer, wherein the conductive super lattice layer includes pairs of at least two semiconductor layers which have compositions different from each other, and the pairs of the at least two semiconductor layers are a periodic repeating of the at least two semiconductor layers; and a second conductive semiconductor layer on the conductive super lattice layer.
