Semiconducting single-walled carbon nanotubes are studied in the diffusive transport regime. The peak mobility is found to scale with the square of the nanotube diameter and inversely with temperature. The maximum conductance, corrected for the contacts, is linear in the diameter and inverse temperature.

Phonon Scattering and Electron Transport in Single Wall Carbon Nanotube

Electron-phonon scattering is studied within an effective-mass theory. A continuum model for acoustic phonons is introduced and electron-phonon interaction due to modification of band structure is derived as well as a normal deformation potential. In a metallic nanotube, the deformation potential does not partic-ipate in electron scattering and a metallic nanotube becomes nearly a one-dimensional ballistic conductor even at room temperature. A resistivity determined by small band-structure interaction depends on the chirality at low temperatures. A magnetic field perpendicular to the axis induces electron scattering by the deformation potential, giving rise to huge positive magnetoresistance. Documents: Advanced Search Include Citations.

Phonon Scattering and Electron Transport in Single Wall Carbon Nanotube

Carbon Nanotubes pp Cite as. The discovery of Novoselov et al. Indeed, recent theoretical studies of graphene reveal that thelinear electronic band dispersion near the Brillouin zone corners gives rise to electronsand holes that propagate as if they were massless fermions and anomalous quantumtransport was experimentally observed. Recent calculations and experimentaldetermination of the optical phonons of graphene reveal Kohn anomaliesat high-symmetry points in the Brillouin zone.
