Abstract: A micro-light-emitting diode array, based on a hexagonal closed-packed structure is presented. Compared to previous designs such as microdisk and microring, the packing density of individual hexagonal elements can be increased to over 80% to minimize wastage of junction area. The increased sidewall area provides additional light extraction pathways. The hexagonal LED emits twice as much light compared to a conventional broad-area LED with equal junction area, and 50% more light than a microdisk array LED. The marked improvement in efficiency makes the additional processing step worthwhile. © 2006 WILEY-VCH Verlag GmbH & Co. KGaA.
