Hot carrier relaxation in GaN:LO phonon scattering and excitonic effects

Hot carrier relaxation has been studied in GaN using femtosecond time-resolved optical transmission and reflection. A non-thermal electron distribution with a pronounced `cut-off' at ELO is observed for up to approximately 3 ps after photoexcitation. Monte Carlo simulations show that this behav...
