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