Original Abstract Submitted
A light emitting diode (LED) pixel array and method of fabrication thereof. A semiconductor wafer template includes a successively stacked first n-GaN layer, first MQW layer, p-GaN layer, and dielectric layer. A plurality of apertures is formed through the dielectric layer, extending to the p-GaN layer. A plurality of mesas is formed by forming, within each aperture, a second MQW layer and a second n-GaN layer above each second MQW layer. The second n-GaN layer and second MQW layer of each mesa form a respective mesa LED with the p-GaN layer. The first n-GaN layer and first MQW layer form a lower LED with the p-GaN layer.
