Large electron-hole exchange interaction of carbon nanotubes

Commentary: Carbon nanotubes, CdSe nanocrystals, and electron-electron interaction.

To celebrate the tenth anniversary of Nano Letters, this short commentary discusses a scientific issue of current interest, increased electron-electron interactions in nanostructures. The two major factors of reduced dimensionality and low screening are analyzed. Carbon nanotubes and graphene are molecular in many of their properties and show strong electron-electron interactions. In specific c...

Lattice dynamics and electron-phonon interaction in (3,3) carbon nanotubes.

We present a detailed study of the lattice dynamics and electron-phonon coupling for a (3,3) carbon nanotube which belongs to the class of small diameter based nanotubes which have recently been claimed to be superconducting. We treat the electronic and phononic degrees of freedom completely by modern ab initio methods without involving approximations beyond the local density approximation. Usi...

Electron-phonon interaction in ultrasmall-radius carbon nanotubes

investigation of the electronic properties of carbon and iii-v nanotubes

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 ...

1 6 O ct 2 00 1 Electron - electron interaction in multiwall carbon nanotubes ⋆

Magnetic susceptibility χ of pristine and brominated arc-produced sample of multi-wall carbon nanotubes was measured from 4.2 to 400 K. An additional contribution ∆χ(T) to diamagnetic susceptibility χ(T) of carbon nanotubes was found at T < 50 K for both samples. It is shown that ∆χ(T) are dominated by quantum correction to χ for interaction electrons (interaction effects-IE). The IE shows a cr...
