Abstract :
A new model for the impact ionization using the tail electron density is proposed. A new hydrodynamic model is used to compute the tail carrier quantities. The discretization method and numerical procedures are explained. The model parameters are extracted from the space-dependent Monte Carlo simulations. The simulated results for an n/sup +/-n/sup -/-n/sup +/ diode and a DILDD n-MOSFET are shown and give good agreement with Monte Carlo simulations and measurements, respectively.<>
