Annotation: This work is devoted to investigation of influence of micro-relief formed on a light output surface of LED produced on optical output coefficient. Simulation results of microrelief on n-GaN layer of GaN/InGaN-based heterostructures of light emitting diode are presented. Optimal geometry of microedges allowing to increase optical output coefficient twofold in comparison to flat light output surface was identified.

Keywords: micro-relief, microedges, optical output coefficient
