High-power InGaN light emitting diodes grown by molecular beam epitaxy

Abstract

The highest power InGaN light emitting diodes produced by molecular beam epitaxy are reported. When operated in continuous-wave mode at room temperature, the optical output power of the devices was 3.75 mW at a forward injection current of 20 mA, and the maximum output power was 14.3 mW. The electroluminescence had a peak at 405 nm and a full width half maximum of 15 nm. The electrical characteristics showed a voltage of 4.8 V and a resistance of 31 Ω at a forward injection current of 20 mA.
