Time-resolved photoluminescences of sample A are shown at temperatures of 35, 75, 150, and . The peak TRPL intensity at different pumping intensities is shown in the inset in (c). The pumping intensity corresponds to a photogenerated carrier concentration of . The solid line is for visual guidance.
The total decay rates for samples A and B are shown at temperatures of 35, 75, 150, and . The temperature dependence of the SRH rates is shown in the inset. The black circle and the red down triangle are for sample A and sample B, respectively.
The Auger rates for samples A and B are shown at (a) and (b) . The black and red lines are the fitted radiative rates for samples A and B, respectively. The inset in (a) shows the temperature dependence of the Auger coefficients. The inset in (b) shows the Auger rates as a function of photogenerated carrier concentration at .
