Quantum transport in carbon nanotubes
In the last twenty years, due to technological advances, it has become possible to build, manipulate and observe nanometer structures and so their dimensions are intermediate between the microscopic and macroscopic. These new systems present novel features and have originated the new field of mesoscopic physics As for the transport properties the mesoscopic conductors do not have ohmic behaviou...
متن کاملQuantum-dot transport in carbon nanotubes
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 clear for measurements of large bias voltage. In addition, we present preliminary results of microw...
متن کاملTransport approach to the superconducting proximity effect in carbon nanotubes
A microscopic approach is developed to account for the magnitudes of the supercurrents observed experimentally in carbon nanotubes placed between superconducting contacts. We build up a model for the nanotube ropes encompassing the electron repulsion from the Coulomb interaction and the effective attraction given by phonon exchange. We show that the available experimental data are consistent wi...

متن کاملSpin-polarized transport through carbon nanotubes
Carbon nanotubes (CNT) belong to the most promising new materials which can in the near future revolutionize the conventional electronics. When sandwiched between ferromagnetic electrodes, the CNT behaves like a spacer in conventional spin-valves, leading quite often to a considerable giant magneto-resistance effect (GMR). This paper is devoted to reviewing some topics related to electron corre...
