摘要: The flip-chip light-emitting diodes (FC-LEDs) with a conductive omni-directional reflector and textured micropillar arrays were investigated. structure was formed on the bottom side of sapphire substrate by dry etching process to increase light-extraction efficiency. light output power FC-LED increased 65% for 3.2-mum substrate. Our work offers promising potential enhancing powers commercial devices.
