| Abstract: | We report fluctuations in resistivity and the
manifestation of Coulomb blockade phenomena of conductive
multiwalled carbon nanotubes under buckling loads.
Individual nanotubes were suspended and soldered between
two indium-dipped tungsten probe tips. Using the electrical
connection between the probes and the nanotube, electrical
measurements were taken with the tube straight (unstrained)
and bent (strained). Typical resistances were in the 10 GΩ
range with resistivities in the 15 to 30 Ω−m range within the
Coulomb blockade region of -1.0 to -0.4 V. Coulomb blockade,
or electron tunneling events, appeared to occur at one of the
contact points. This effect was diminished or lost once the
carbon weld was broken. |
