The ensemble Monte Carlo method is used to calculate the velocity–field characteristics in highly doped GaAs. A new technique is developed in order to include into Monte Carlo simulations electron interactions with coupled plasmon–polar optical phonon modes. Calculations are performed for an electron concentration level equal to 7×1017 cm-3. Results of simulations are compared with model when coupling is neglected. Various models of screening length and screening by nonequilibrium electron gas are also considered.
