Our results show that the carrier lifetime varies as recombination evolves, with faster decay rates at the initial stages (with lifetime of ${\\sim 800}\\,$ps), and much slower lifetimes at later stages (up to ${\\sim 300}\\,$ns). We also observe experimentally the effect of trapping, manifesting as a decay curve highly dependent on the initial carrier density.
