Abstract

The transient expansion process of a photogenerated electron-hole plasma is examined using Ensemble Monte Carlo techniques. The effect of nonequilibrium phonons on the expansion behaviour is included for the first time. Both the spatial and temporal variations of the phonon population are taken into account. Numerical results over the picosecond time scale demonstrate that the nonequilibrium phonons significantly enhance the plasma expansion and alter the spatial carrier distribution profiles.
