Conduction mechanisms and magnetotransport in multiwalled carbon nanotubes

S. Roche, F. Triozon, A. Rubio, D. Mayou

We report on a numerical study of quantum diffusion over μm lengths in defect-free multiwalled nanotubes. The intershell coupling allows the wave packet spreading over several shells, and when their periodicities along the nanotube axis are incommensurate, electronic propagation is shown to follow a nonballistic law if a sufficient number of shells are involved in conduction. This results in magnetotransport properties which are exceptional for a disorder free system.
