We model the dynamics of carriers injected into a semiconductor quantum well during femtosecond photoexcitation using an ensemble Monte Carlo simulation which includes two-dimensional electron-electron scattering. The time evolution of the nonequilibrium electron distribution is used to calculate the time dependence of the multi-subband dielectric matrix during the simulation so that transient effects in the screening are incorporated into the inter-carrier scattering rate. Our results show that band filling occurs within 200fs for small injection energies, the rate of which increases with increasing injection density.
