Abstract :
Simple analytical formulas are presented for the current flowing through a single atom located between a pair of metallic electrodes and the number of electrons bound in the atom. The work function of the electrodes W, the highest occupied energy level of the atom -E0 , and the electrostatic charging energy U, determine how the atom becomes charged and how the current features nonlinearity via the Coulomb blockade and the Pauli exclusion principle
