Propagative Landau States and Fermi Level Pinning in Carbon Nanotubes
Stephan Roche, member of the Theory and Simulation Group at CIN2 (CSIC-ICN), together with other researchers from Université de Toulouse, Universidad Autónoma de Madrid and Commissariat à l'Energie Atomique published 'Propagative Landau States and Fermi Level Pinning in Carbon Nanotubes' on Phys. Rev. Lett.
They present strong evidence of Landau states formation in multiwalled carbon nanotubes with metallic or semiconducting outer shells, under magnetic fields as high as 60 T. Magnetoconductance data are found to converge to a gate-independent value for semiconducting shells, whereas for metallic shells, the Landau states introduce a strong reintroduction of backscattering and Fermi level pinning close to the charge neutrality point. Electronic band structure and transport calculations provide a consistent interpretation of the experimental data.
