## Abstract We use Raman scattering to investigate the folded longitudinal acoustic (LA) phonons in a series of In~__x__~Ga~1−__x__~N/GaN superlattices (SLs) grown by molecular beam epitaxy with different compositions (15% < __x__ < 38%) and SL periods (from 8 to 20 nm). A novel, ultralow wavenumbe
