摘要：

We present an ensemble Monte Carlo simulation of electronic transport in p-type In0.53Ga0.47As. The effects of mixed phonon modes and of dynamically screened electron-hole scattering on the velocity-field characteristics are examined. Our results show that a two phonon model yields smaller velocities at low fields and higher values beyond the intervalley transfer threshold. The dynamic screening leads to a field dependent velocity enhancement at moderate carrier densities.
