Single-electron Faraday generator

G. González


In this paper I study the posibility of inducing a single-electron current by rotating a non-magnetic conducting rod with a small tunnel junction immerse in a uniform magnetic field perpendicular to the plane of motion. I show first, by using a thermodynamic approach, the conditions needed to pump electrons around the mechanical device in the Coulomb blockade regime. I then use a density matrix approach to describe the dynamics of the single-charge transport including many-body effects. The theory shows that it is possible to have single-electron tunneling (SET) oscillations at low temperatures by satisfying conditions similar to the Coulomb blockade systems.
