Micro-LEDs have attracted attention in recent years as a next-generation display technology.
In this study, multicolor stacked micro-LEDs of InGaN quantum well LEDs and GaN:Eu red LEDs were fabricated using tunnel junction contacts to realize a stacked micro-LED display. The use of tunnel junctions is also shown to be a useful method for micro-LED integration of multicolor stacked micro-LEDs of InGaN quantum well LEDs and GaN:Eu red LEDs.
