  • We report a firm evidence of enhanced luminescence from InGaN-like clusters in InxAlyGa1−x−yN quaternary alloys. Photoluminescence (PL) and Raman scattering measurements have been employed to study the optical properties of these alloys. The excellent correlation between the phonon replica structures accompanying luminescence line and the observed InGaN-related phonon modes in Raman spectra provide a powerful evidence showing that the existence of InGaN-like clusters is responsible for the… CONTINUE READING
