摘要：

We model time-resolved photoluminescence in GaAs using an ensemble Monte Carlo method coupled with a k.p calculation of the band structure. We show that on a picosecond scale, carrier diffusion perpendicular to the layer significantly reduces the density at the surface and consequently has a first-order effect on luminescence measurements. To illustrate this we compare the calculated luminescence, with and without diffusion, to experimental data.
