Abstract
We report the fabrication of an epitaxial lateral overgrown (ELO) GaInN layer on a high crystalline-quality-grooved GaN template, which is improved by a sidewall ELO (SELO) technology. The photoluminescence peak intensity of ELO-grown GalnN layer on the SELO GaN underlying layer is twice as high as that of ELO-grown GalnN layer on the m-plane GaN template.
