250-280 nm-band high-efficiency deep-ultraviolet (DUV) light-emitting diodes (LEDs) and laser diodes (LDs) are attractive much attention for the application to sterilization or medical use. The realization of low threading dislocation density (TDD) AlN template on sapphire substrate is considerably important in order to realize high-efficiency and high-power AlGaN-based DUV-LEDs. In this work, we fabricated AlGaN quantum well (QW) LEDs on Low TDD AlN template fabricated by epitaxial lateral overgrowth (ELO) method, and realized CW milliwatt power operation of AlGaN DUV-LED. First we grew initial AlN on c-plane sapphire substrate by using ammonia (NH3) pulse-flow multilayer (ML) growth method. After we formed 5/3 μm AlN stripes on the initial AlN, we grew thick ELO-AlN layer. We fabricated the AlGaN-3QWs LED on the ELO-AlN. Intense 273 nm emission peak was obtained from the AlGaN LED, and the maximum output power was 2.7mW, the maximum external quantum efficiency (EQE) was 0.04%. |
