Abstract

Nonpolar a-plane light emitting diodes (LEDs) in InGaN/GaN multiple quantum well structures were successfully fabricated by metal organic chemical vapour deposition (MOCVD) on r-plane sapphire substrates. An optical output power of 0.26 mW was obtained at a drive current of 20 mA and 1.27 mW at 100 mA, with peak emission wavelengths of 504.5 nm and 503.9 nm, respectively. The peak emission wavelength shift for the green LED was 4.4 nm when the injection current was changed from 5 to 100 mA.
