Carbon nanotubes have been regarded since their discovery1 as potential molecular quantum wires. In the case of multi-wall nanotubes, where many tubes are arranged in a coaxial fashion, the electrical properties of individual tubes have been shown to vary strongly from tube to tube2,3, and to be characterized by disorder and localization4. Single-wall nanotubes5,6 (SWNTs) have recently been obtained with high yields and structural uniformity7. Particular varieties of these highly symmetric… 
Carbon nanotubes as long ballistic conductors
Early theoretical work on single-walled carbon nanotubes predicted that a special achiral subset of these structures known as armchair nanotubes should be metallic. Tans et al. have recently
Electron–electron correlations in carbon nanotubes
Single-wall carbon nanotubes, are ideally suited for electron-transport experiments on single molecules because they have a very robust atomic and electronic structure and are sufficiently long to
Electronic structure of atomically resolved carbon nanotubes
Carbon nanotubes can be thought of as graphitic sheets with a hexagonal lattice that have been wrapped up into a seamless cylinder. Since their discovery in 1991, the peculiar electronic properties
Electron transport in very clean, as-grown suspended carbon nanotubes
The clean transport data show a correlation between the contact junction resistance and the various transport regimes in single-walled-carbon-nanotube devices, and electrical transport data can be used to probe the band structures of nanotubes, including nonlinear band dispersion.
Single‐Walled Carbon Nanotubes
Spectroscopic studies of ultrasmall magnetic nanostructures, consisting of small cobalt clusters on short nanotube pieces, exhibited features characteristic of the bulk Kondo resonance, but also new features due to their finite size.
Electrical characterization of the mutual influences between gas molecules and single-walled carbon nanotubes.
It is demonstrated that in addition to the morphology, the transport properties of CNTs can also be modified in this manner, and a significant reduction of the resistance in SWNT devices is shown by such current-induced annealing (CIA) due to the removal of gas molecules from the SWNTs.
Carbon nanotube intramolecular junctions
The ultimate device miniaturization would be to use individual molecules as functional devices. Single-wall carbon nanotubes (SWNTs) are promising candidates for achieving this: depending on their
Carbon nanotube quantum dots
Low temperature electron transport measurements on individual single wall carbon nanotubes are described in this thesis. Carbon nanotubes are small hollow cylinders made entirely out of carbon atoms.
Broken symmetry and pseudogaps in ropes of carbon nanotubes
Since the discovery of carbon nanotubes, it has been speculated that these materials should behave like nanoscale wires with unusual electronic properties and exceptional strength. Recently, ‘ropes’
Kondo physics in carbon nanotubes
It is reported that electrically contacted single-walled carbon nanotubes can serve as powerful probes of Kondo physics, demonstrating the universality of the Kondo effect.


Electrical conductivity of individual carbon nanotubes
THE interest in carbon nanotubes has been greatly stimulated by theoretical predictions that their electronic properties are strongly modulated by small structural variations1–8. In particular, the
Single-shell carbon nanotubes of 1-nm diameter

Crystalline Ropes of Metallic Carbon Nanotubes
X-ray diffraction and electron microscopy showed that fullerene single-wall nanotubes (SWNTs) are nearly uniform in diameter and that they self-organize into “ropes,” which consist of 100 to 500 SWNTs in a two-dimensional triangular lattice with a lattice constant of 17 angstroms.
Cobalt-catalysed growth of carbon nanotubes with single-atomic-layer walls
CARBON exhibits a unique ability to form a wide range of structures. In an inert atmosphere it condenses to form hollow, spheroidal fullerenes1–4. Carbon deposited on the hot tip of the cathode of
Quantum transport in a multiwalled carbon nanotube.
Electrical resistance measurements of an individual carbon nanotube down to a temperature T = 20 mK find a global and coherent interpretation in terms of two-dimensional weak localization and universal conductance fluctuations in mesoscopic conductors.

It is estimated that the mean-field transition temperature from a Peierls-distorted regime to a high-temperature metallic regime should be well below room temperature.
New one-dimensional conductors: Graphitic microtubules.
It is predicted that carbon microtubules exhibit striking variations in electronic transport, from metallic to semiconducting with narrow and moderate band gaps, depending on the diameter of the tubule and on the degree of helical arrangement of the carbon hexagons.
