Injection statistics simulator for dynamic analysis of noise in mesoscopic devices

摘要

We present a model for electron injection from thermal reservoirs, which is applied to particle simulations of one-dimensional mesoscopic conductors. The statistics of injected carriers is correctly described from non-degenerate to completely degenerate conditions. The model is validated by comparing Monte Carlo simulations with existing analytical results for the case of ballistic conductors. An excellent agreement is found for the average and noise characteristics, in particular, the fundamental unities of electrical and thermal conductances are exactly reproduced.
