Abstract:Micro-pixelated GaN light-emitting diodes (‘micro-LED’s) offer attractions for a wide range of applications including microdisplays, mask-free photolithography, lab-on-a-chip and bioinstrumentation [1]. Mesa dry etching methods have underpinned the development of this technology to date. Here we propose and demonstrate a new planar process which simplifies the process flow and permits individually-addressable pixelated devices to be fabricated without any obvious degradation of electrical and optical performan… Show more
