Electronic conduction in multi-walled carbon nanotubes: role of intershell coupling and incommensurability

Abstract Geometry incommensurability between weakly coupled shells in multi-walled carbon nanotubes is shown to be the origin of unconventional electronic conduction mechanism, power-law scaling of the conductance, and remarkable magnetotransport and low temperature dependent conductivity when the dephasing mechanism is dominated by weak electron–electron coupling.
