Ballistic Transport in Metallic Nanotubes with Reliable Pd Ohmic Contacts

  title={Ballistic Transport in Metallic Nanotubes with Reliable Pd Ohmic Contacts},
  author={David Mann and Ali Javey and Jing Kong and Qian Wang and Hongjie Dai},
Contacting metallic single-walled carbon nanotubes by palladium (Pd) affords highly reproducible ohmic contacts and allows for the detailed elucidation of ballistic transport in metallic nanotubes. The Pd ohmic contacts are more reliable than the titanium (Ti) previously used for ballistic nanotube devices. In contrast, Pt contacts appear to give nonohmic contacts to metallic nanotubes. For both ohmic and nonohmic contacts, the length of the nanotube under the metal contact area is electrically… CONTINUE READING
