Abstract:
1. A method of manufacturing a group III nitride nanorod light emitting device, the method comprising: forming a first conductive semiconductor layer on a substrate forming an insulating film including openings exposing parts of the first conductive semiconductor layer; growing first conductive group III nitride nanorods, respective diameters of the first conductive group III nitride nanorods being 120 nm or greater; and forming light emitting structures by sequentially forming an active layer and a second conductive semiconductor layer on a surface of each of the first conductive group III nitride nanorods such that the active layer is positioned on a side surface of the first conductive group III nitride nanorod, wherein the light emitting structures are divided into at least two groups including a first group on a first area of the first conductive semiconductor layer and a second group on a second area of the first conductive semiconductor layer, each group including two or more light emitting structures that have substantially identical diameters and substantially identical heights, wherein the diameter of the light emitting structures of the first group is smaller than the diameter of the light emitting structures of the second group and an active layer of the second group emits second light having a different wavelength from that of the first light emitted by an active layer of the first group, and wherein the active layer of the second group has an indium (In) content smaller than that of the active layer of the first group.
