Extended Hückel theory for electronic transport in carbon nanotubes with metal contacts
In the present work we use a selfconsistent version of the EHT to study the electronic transport in metallic carbon nanotubes (CNTs) with various metallic electrodes (Al, Cu, Pd, Pt, Ag, Au). While the electronic structure of the metals is well described by the extended Hückel (EH) parameters of Cerdá [1], we show that a new parameter set for carbon strongly improves the agreement between EHT a...
متن کاملNarrow-gap Luttinger liquid in carbon nanotubes.
Electron interactions reinforce minigaps induced in metallic nanotubes by an external field and turn the gap field dependence into a universal power law. An exactly solvable Gross-Neveau model with an SU(4) symmetry is derived for neutral excitations near half filling. Charge excitations, described by a sine-Gordon perturbation of Luttinger liquid theory, are composite solitons formed by the ch...
متن کاملNarrow Carbon Nanotubes: Metals or Semiconductors?
We report local density functional results that show that narrow nanotubes with optimized diameters between about 0.34 and 0.5 nm can be either semiconducting or metallic, but with electron structures near the Fermi level that often cannot be understood starting from the graphene sheet model, successful in the study of larger diameter tubes. Our total energy calculations indicate that narrow na...

ply a similar model. When using an electron beam instead of an ion beam, the CNTs could not be aligned, which indicates that the mass of the charge carrier is possibly involved in the process. The CNT aligned by this method maintains its elasticity, as is observed in the bending test with a nanomanipulator installed in the scanning electron microscope. Furthermore, we could obtain stable SFM im...

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
