1. An apparatus, comprising:
- a structure comprising an n-type group III-nitride layer and a p-type group III-nitride layer and a junction between the n-type and the p-type group III-nitride layers therein, the structure having a plurality of pyramids of group III-nitride; and
wherein a quantum well is located at the junction, andwherein a continuous surface of one of the n-type group III-nitride layer and the p-type group III-nitride layer forms outer surfaces of at least two of the pyramids.

11. An apparatus, comprising:
-
a plurality of crystalline structures being located on a substrate and being configured to emit light, each of the structures having an n-type barrier region and a p-type barrier region and a junction there between, the junction being located at surfaces of the n-type and the p-type barrier regions, said surfaces being inclined with respect to the substrate, wherein one of the n-type barrier regions and the p-type barrier regions are continuously interconnected through a planar base portion of the same one of the n-type barrier regions and the p-type barrier regions, the planar base portion being located on the substrate, and the other of the n-type barrier regions and the p-type barrier regions comprise a continuous outer layer that continuously coats the inclined surfaces of at least two of the structures, and wherein the inclined surfaces form pyramidal shapes. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
