Four-probe measurements of carbon nanotubes with narrow metal contacts

Published

Journal Article

We find that electrons in single-wall carbon nanotubes may propagate substantial distances (tens of nanometers) under metal contacts. We perform four-probe transport measurements of the nanotube conductance and observe significant deviations from the standard Kirchhoff's circuit rules. Most noticeably, injecting current between two neighboring contacts on one end of the nanotube induces a nonzero voltage difference between two contacts on the other end. © 2007 The American Physical Society.
