Light emitting diode with zinc oxide layer and method of fabricating the same
A light emitting diode with a zinc oxide layer and a method of fabricating the same are disclosed. The light emitting diode includes: a light emitting structure including a gallium nitride based first conductivity type semiconductor layer, a gallium nitride based second conductivity type semiconductor layer, and an active layer interposed therebetween; and a ZnO transparent electrode layer disposed on the second conductivity type semiconductor layer, wherein the ZnO transparent electrode layer comprises a ZnO seed layer and a ZnO bulk layer formed on the ZnO seed layer, wherein the ZnO bulk layer is porous compared to the ZnO seed layer, wherein an interface between the ZnO seed layer and the second conductivity type semiconductor layer is flatter than an interface between the ZnO seed layer and the ZnO bulk layer, and wherein the interface between the ZnO seed layer and the ZnO bulk layer has an irregular concavo-convex shape.
