Highly efficient gallium nitride based light emitting diodes via surface roughening
TL;DR: A gallium nitride (GaN) based light emitting diode (LED), wherein light is extracted through a nitrogen face (N-face) of the LED and a surface of the N-face (42) is roughened into one or more hexagonal shaped cones as discussed by the authors.
Patent
Highly efficient group-III nitride based light emitting diodes via fabrication of structures on an N-face surface
TL;DR: In this paper, a gallium nitride (GaN) based light emitting diode (LED) was used to extract light through a nitrogen face (N-face) of the LED and a surface of the N-face was roughened into one or more hexagonal shaped cones.
