Wigner Monte Carlo Approach to Quantum Transport in Nanodevices

摘要

The Wigner Monte Carlo approach is shown to provide an efficient way to study quantum transport in the presence of scattering and to connect semi-classical to quantum transport. The study of resonant tunneling diodes highlights the physics of the impact of scattering on resonant tunneling, and on electron decoherence and localization. The simulation of nano-MOSFET evidences a mixed regime, where both quantum transport and scattering play a significant role.
