Abstract
Disclosed herein is a light emitting device. The light emitting device includes an n-type nitride semiconductor layer; an active layer on the n-type semiconductor layer, an AlN/GaN layer of a super lattice structure formed by alternately growing an AlN layer and a GaN layer on the active layer, and a p-type nitride semiconductor layer on the AlN/GaN layer of the super lattice structure. At least one of the AlN layer and the GaN layer is doped with a p-type dopant. A method for manufacturing the light emitting device is also provided.
