Resonance transmission through a single atom
When a single atom is sandwiched in between two electrodes, an atomic tunneling device may be realized depending on the distance between the atom and the electrodes. We have performed first-principles pesudopotential calculation in conjunction with a three-dimensional evaluation of the quantum scattering matrix for such a device. We predict the quantum conductance and resonance transmission properties of the Si and Al atomic tunneling devices.
