Paper Abstract

InxAlyGa1-xN quaternary alloys with different In and Al composites were grown on sapphire substrates with GaN buffer by metal-organic chemical vapor deposition. Optical properties of these quaternary alloys were studied by picosecond time-resolved photoluminescence. Our studies have revealed that InxAlyGa1-xN quaternary alloys with lattice matched with GaN (y approximately 4.7x) have the highest optical quality. More importantly, we can achieve not only higher emission energies but also higher emission intensities (or quantum efficiencies) in InxAlyGa1-x-yN quaternary alloys than that of GaN.
