Carbon Nanotube Millikelvin Transport and Nanomechanics.

Single-walled carbon nanotubes cooledo cryogenic temperatures are outstanding electronic as well as nanoelectrnmechanical model systems.To probe a largely unperturbed system,e measure a suspended carbonnanotube device where the nanotube isgo n in the last fabrication step, thus avoiding damage and residues fromsubsequentprocessing,In this ultra -clean device, we observe the transport spectrumand its n on nanoelectromechanics over a wide gate voltage range and thereby over a wide range of oupling parametersbetween the quantum dot and the contai electrodesa.
