On the applicability of nonself-consistent Monte Carlo device simulations

Recently, nonself-consistent (with respect to the electric field) Monte Carlo (NSC-MC) simulations have been proposed for the estimation of the noise and expected value of stationary terminal currents without examining the accuracy of the NSC approximation for these kinds of simulations. Comparison with self-consistent (SC) simulations reveals that NSC simulations of quantities like the drain current of a MOSFET or collector current of a BJT tend to reproduce the results of the momentum-based model used to calculate the electric field without improving the accuracy. In case of terminal current noise it is found that under nonequilibrium conditions the NSC results can substantially overestimate the SC results.
