Abstract:
1. A light emitting diode, comprising: an epitaxial layer structure; a first electrode; and a second electrode, wherein the first and second electrodes are disposed on one side of the epitaxial layer structure, and the epitaxial layer structure comprises a transparent ohmic contact layer having a root-means-square (RMS) roughness less than about 3 nm at a surface whereon the second electrode is formed, wherein the epitaxial layer structure includes a p-type epitaxial layer and a n-type epitaxial layer, wherein the n-type epitaxial layer is coupled between the first electrode and the p-type epitaxial layer, and the p-type epitaxial layer is between the second electrode and the n-type epitaxial layer, and wherein the first electrode is located on the n-type epitaxial layer.
