| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A connected-pillar AlN buffer structure fabricated on sapphire substrate is considered to be quite effective for increasing efficiency of AlGaN based deep-ultraviolet (DUV) LEDs, because of improving internal quantum efficiency (IQE) due to reduced threading-dislocation density (TDD), and light-extraction efficiency (LEE). In this study, we demonstrated the fabrication of connected-pillar AlN structure buffer on patterned-sapphire substrates (PSS) by using an ‘NH3 pulsed flow multi-layer growth’ method and an epitaxial lateral overgrowth (ELO). We obtained output power of 5.5 mW from 265 nm AlGaN-based DUV-LED fabricated on connected-pillar AlN buffer on PSS under room temperature CW operation. | |
