Wigner Monte Carlo Simulation of CNTFET: Comparison Between Semi-Classical and Quantum Transport
This paper examines the quantum transport effects in carbon nanotube field-effect transistors (CNTFETs) within the Wigner's function formalism, using a particle Monte Carlo technique. The comparison with semi-classical simulation shows that significant differences observed at the microscopic level are not necessarily strongly reflected at the macroscopic level in terms of drain current. The dependence of quantum effects on gate length is also investigated.
