Abstract

The optical properties of InGaN quantum wells on misoriented GaN (0001) substrates were investigated. The fluctuation of peak wavelength and full width at half maximum of micro-photoluminescence from InGaN quantum wells was large when the misorientation angle was 0.0^o. The micro-photoluminescence showed narrow-width spectra, with full width at half maximum below 60 meV, of InGaN quantum wells grown on GaN (0001) substrates with a misorientation angle of around 0.28^o toward [1₁^-00] direction. These results indicate that InGaN quantum wells have high crystalline quality when InGaN quantum wells are grown with misorientation angle between 0.2^o and 0.3^o toward [1₁^-00] direction.
