We report four-probe I–V
measurements on individual vertically aligned carbon nanofibers
(VACNFs). These measurements were enabled by the fabrication of
multiple Ti/Au ohmic contacts on individual fibers that
exhibited resistance of only a few kilohms. These
measurements demonstrate that VACNFs exhibit linear I–V
behavior at room temperature, with a resistivity of
approximately 4.2×10–3
cm. Our measurements are consistent with a dominant transport
mechanism of electrons traveling through intergraphitic planes in the
VACNFs. ©2004 American Institute of Physics.
