Abstract
In this study, the transport characteristics of multiwalled carbon nanotubes were measured at low temperatures using the multiple-probe technique. Cr metal was used as the electrode material and good Ohmic contact to the tube was obtained. Measurements using two- and four-probe techniques showed Coulomb oscillation with nearly the same period, indicating that the local islands formed inside the nanotube. Our experiments and simulation results suggested that the local barriers existing between electrodes divided our tube into a chain of weakly coupled islands and were responsible for the observed Coulomb blockade behaviors.
