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 of these structures have attracted much attention. Their electronic conductivity, for example, has been predicted to depend sensitively on tube diameter and wrapping angle (a measure of the helicity of the tube lattice), with only slight differences in these parameters causing a shift from a metallic… 
Geometrical structure and electronic properties of atomically resolved multiwall carbon nanotubes
Multiwall carbon nanotubes (MWNTs) are predicated to exhibit various electronic properties depending on their diameters and chiralities. The existence of multishells offers the possibility of

A detailed three-dimensional structural analysis of single-walled carbon nanotubes was carried out using a scanning tunneling microscope (STM) operated at room temperature in ambient conditions. On a
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.
Tuning the band structure of carbon nanotubes
The experiments presented in this thesis show that carbon nanotube (NT) electronic structure can be tuned by mechanical stretching and by magnetic fields. These fascinating electromechanical and

The nanometer dimensions of the carbon nanotubes together with the unique electronic structure of a graphene sheet make the electronic properties of these one-dimensional structures highly unusual.

Individual single-wall carbon nanotubes as quantum wires
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

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
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.
