Carbon nanotubes of high intrinsic resistivity have been studied. The conductance of the nanotubes has been measured as a function of voltage and temperature. The results on a sample, whose contact resistances nearly equal the resistance of the tube itself, are interpreted in terms of strong tunneli

โฆ Synopsis
Single-walled carbon nanotubes -nanometer diameter graphene cylinders -are a new class of one-dimensional (1 D) conductors.
Recent STM[l] and transport[2-81 experiments have shown that these tubes can be either semiconductors or 1D metals. Here we review our group's recent electrical studies[3-51 of these novel 1D conductors.

We present transport measurements of ferromagnetically contacted carbon nanotubes. In both single-and multi-walled nanotube devices, a spin valve effect is observed due to spin-polarized transport. In one single-walled nanotube device, the spin-valve effect is suppressed as the influence of Coulomb
Transport measurements on a bundle of single-walled carbon nanotubes have been made below 4.2 K as a function of side gate and source-drain bias voltage. The transport of an individual nanotube is described by the Coulomb blockade effect. The zero-dimensional quantum states of the nanotube become cl
