Abstract:
1. A light emitting diode, comprising: a first semiconductor layer; a second semiconductor layer having a light emitting surface; an active layer located between the first semiconductor layer and the second semiconductor layer, the light emitting surface being away from the active layer; a first electrode electrically connected with the first semiconductor layer; a second electrode electrically connected with the second semiconductor layer; and a plurality of three-dimensional nano-structures located on a surface of the first semiconductor layer away from the active layer, wherein each of the plurality of three-dimensional nano-structures comprises a first peak and a second peak aligned side by side, a first groove defined between the first peak and the second peak, and a second groove defined between each two adjacent three-dimensional nano-structures of the plurality of three-dimensional nano-structures, a depth of the first groove being less than a depth of the second groove.
