AbstractSince the discovery of carbon nanotubes by Iijima in 1991, various carbon nanotubes with either a single‐ or multilayered graphene cylinder(s) have been produced, along with their noncarbon counterparts (for example, inorganic and polymer nanotubes).

He atoms in carbon nanotubes and nanotube bundles
Physical Review B, 2004We report results for the energetics and single-particle spectra of $^4$He and $^3$He atom confined by one, two, and three carbon nanotubes, obtained using both a smooth--tube model for the interaction between helium atoms and tubes, and a realistic model that takes the atomic structure of the tubes into account.

Thermal conductivity in nanotubes and nanotube bundles
2005Nanotubes show a very interesting behaviour of lattice thermal conductivity depending on the tube diameter, with very high thermal conductivities for small diameters. In bundles of nanotubes, the thermal conductivity is affected by the reduced dimensionality of the phonon system.

Perspective of nanotube sensors and nanotube actuators
4th IEEE Conference on Nanotechnology, 2004., 2005The state of the art of nanotube sensors and nanotube actuators are overviewed according to the physical properties/effects (large aspect ratio, ultra-high elasticity, lower onset field emission, ultra-small interlayer friction, etc.) applied, number of nanotubes (single, double or multiple-array, fiber, film and bulk) involved, and configurations of ...

Carbon nanotube motors driven by carbon nanotube
The Journal of Chemical Physics, 2008We propose a new type of carbon nanotube (CNT) motor composed of a single-wall CNT (SWCNT) and a double-wall CNT (DWCNT), that are in mechanical contact. The rotational motion of our CNT motor is controllable by the translational motion of the SWCNT along the axis of the DWCNT.

Mechanics of nanotubes and nanotube-based devices
AIP Conference Proceedings, 2003We discuss the mechanical properties of carbon nanotubes and devices incorporating carbon nanotubes. We demonstrate novel measurement and force application techniques using an atomic force microscope coupled to a unique computing environment that simplifies manipulations.

Deformation of carbon nanotubes in nanotube–polymer composites
Applied Physics Letters, 1999Composites of uniaxially oriented multiwalled carbon nanotubes embedded in polymer matrices were fabricated and investigated by transmission electron microscopy. In strained composite films, buckling was ubiquitously observed in bent nanotubes with large curvatures. By analyses of a large number of bent nanotubes, the onset buckling strain and fracture

Contact Transparency of Nanotube-Molecule-Nanotube Junctions
Physical Review Letters, 2007The transparency of contacts between conjugated molecules and metallic single-walled carbon nanotubes is investigated using a single-particle Green's function method which combines a Landauer approach with ab initio density functional theory. We find that the overall conjugation required for good contact transparency is broken by connecting through a ...
