摘要：
Photo-excited carrier relaxation dynamics in InN films were investigated using femtosecond transient measurements. We measured two samples with different background carrier densities, and discussed the influence of the carrier densities on the relaxation dynamics. We also found that the slow decay component disappears under the optimized condition because of the effects of equilibrium band filling and bandgap renormalization.
