Abstract

A method of manufacturing an apparatus, comprising forming a light-emitting crystalline structure. Forming the light-emitting crystalline structure includes forming a first barrier region on a substrate, the first barrier region having one or more inclined surfaces relative to a planar surface of the substrate. Forming the light-emitting crystalline structure also includes forming a second barrier region over the first barrier region, to form a junction at the inclined surfaces, wherein the first barrier region comprises one of an n-type or p-type semiconductor crystal, and the second barrier region comprises the other of the n-type or p-type semiconductor crystal.

Claims

3-1. The method of claim 1, wherein forming the first barrier region comprises forming a plurality of interconnected wedge-shaped portions on a base portion, the wedge-shaped portions and the base portion comprising a same material of the first barrier region.
