Abstract:
1. A method for fabricating a light emitting diode (LED) using three-dimensional gallium nitride (GaN) pillar structures with planar surfaces, the method comprising; forming a plurality of GaN pillar structures, each GaN pillar structure being formed as follows: depositing the plurality of GaN pillar structures on a first substrate, with the n-doped GaN pillar sidewalls aligned parallel to a top surface of the first substrate; connecting a first end of each GaN pillar structure to a first metal layer to form a first electrode; etching a second end of each GaN pillar structure to expose the n-GaN pillar second end; and, subsequent to etching the second end of each GaN pillar structure, connecting the second end of each GaN pillar structure to a second metal layer to form a second electrode.
