title: Nonlinear transport through a nanoscale molecule.
abstract: A simple model of electrical transport through a metal-aromatic molecule-metal system that includes charging effects as well as aspects of the electronic structure of the molecule, is presented. The interplay of a large charging energy and an asymmetry of the metal-molecule coupling can lead to various effects in nonlinear electrical transport. In particular, strong negative differential conductance is observed under certain conditions.
