Abstract
We report on the onset of Landau-level formation in a carbon nanotube-based Fabry-Perot resonator. Supported by excellent agreement between calculated and measured magnetoconductance patterns, the applied perpendicular magnetic field is shown to modulate the Fabry-Perot conductance oscillations consistently with the formation of a Landau level in the 1D massless Dirac fermions particle excitations.

Synopsis
Landau levels in a nanotube
Published 6 August 2008
The formation of Landau levels in a magnetic field is the hallmark of a two-dimensional electron system, such as graphene. Experiments now suggest that Landau levels can also form in carbon nanotubes.
