Low-temperature transport through suspended single-wall nanotube resonators — •Daniel Schmid, Dominik Preusche, Christoph Strunk, and Andreas K. Hüttel — Institute for Experimental and Applied Physics, University of Regensburg, 93040 Regensburg, Germany

Suspended carbon nanotubes not only present fascinating electronic properties, but also provide excelling high-frequency and low-dissipation mechanical resonators. In addition, recent work has shown direct strong interaction between electronic tunneling and mechanical motion in the Coulomb blockade regime. We present results on transport through such nano-electromechanical devices at ultra-low temperature, using a recently developed technique to detect the nanomechanical motion in dc current signals. Different contact metals are discussed for their influence on electronic transport and their suitability.
