Coherent charge transport through molecular wires: influence of strong Coulomb repulsion
arXiv:cond-mat/0505680 · doi:10.1016/j.chemphys.2005.08.005
Abstract
We derive a master equation for the electron transport through molecular wires in the limit of strong Coulomb repulsion. This approach is applied to two typical situations: First, we study transport through an open conduction channel for which we find that the current exhibits an ohmic-like behaviour. Second, we explore the transport properties of a bridged molecular wire, where the current decays exponentially as a function of the wire length. For both situations, we discuss the differences to the case of non-interacting electrons.
