Rectification of displacement currents in an adiabatic electron pump
arXiv:cond-mat/0012249 · doi:10.1103/PhysRevB.63.121303
Abstract
Rectification of ac displacement currents generated by periodic variation of two independent gate voltages of a quantum dot can lead to a dc voltage linear in the frequency. The presence of this rectified displacement current could account for the magnetic field symmetry observed in a recent measurement on an adiabatic quantum electron pump by Switkes et al. [Science 283, 1905 (1999)].
