Patent ID: 8759130

Claim:
A method for making a light emitting diode, the method comprising: providing a substrate having a first epitaxial growth surface; placing a carbon nanotube layer on the first epitaxial growth surface of the substrate; epitaxially growing a first semiconductor layer on the first epitaxial growth surface; exposing a surface of the first semiconductor layer by removing the substrate and the carbon nanotube layer, wherein the surface of the first semiconductor layer is defined as a second epitaxial growth surface; growing an active layer and a second semiconductor layer on the second epitaxial growth surface in that order, wherein a surface of the active layer contacting the first semiconductor layer engages with the second epitaxial growth surface; exposing a part of the first semiconductor layer by etching a part of the active layer and the second semiconductor layer; and applying a first electrode on the first semiconductor layer and applying a second electrode on the second semiconductor layer.
