Surface plasmon polariton induced effects onto the electronic transport through gold point contacts — •Philipp Nürnberger, Daniel Benner, Johannes Boneberg, Paul Leiderer, and Elke Scheer — Department of Physics, University of Konstanz, Germany

We study the impact of cw laser illumination onto the electronic transport through gold point contacts realized by Mechanically Controllable Break-junction (MCBJ) technique. For that purpose we excite surface plasmon polaritons at a grating, milled into the leads of the constriction. The excitation is controlled by an arrangement of additional gratings framing the constriction. Finally we compare the optical signal with the electronic response of the MCBJ.
