Abstract :
A theoretical model of Impact Ionization rate is proposed in this paper. Multistage scattering processes are considered which incorporate electron-electron scattering, hole-hole scattering, optical phonon scattering and impact ionization. The effect of high carrier concentration on carrier mobility and effective mass has been taken into account and the resulting modification in the ionization rate has been incorporated. The proposed theoretical model is simulated for GaAs and the results are found to be in close agreement with available experimental results.
