Experiment performed on a 10 period GaN/Al0.07Ga0.93N quantum well structure suggests that the ratio of unconfined to confined band contribution to the photoluminescence varies from 10% to 40% when the pump intensity is increased by an order of magnitude. To understand these processes, the dynamics of carrier transport from the barrier to the well regions was probed using picosecond time-resolved PL spectroscopy at different pumping intensities and temperatures. The spectral data were analyzed, thus determining the time evolution of the carrier distributions.
