Abstract

Decay of the longitudinal optical (LO) phonons in wurtzite GaN has been studied by subpicoseond time-resolved Raman spectroscopy. Our experimental results show that, among the various possible decay channels, the LO phonons in wurtzite GaN decay primarily into a large wavevector TO and a large wavevector LA or TA phonons. These experimental results are consistent with the recent theoretical calculations of the phonon dispersion curves for wurtzite GaN.
