Probing magneto-transport properties of carbon nanostructures in pulsed magnetic fields

We present the magnetoconductance of carbon nanostructures (including carbon nanotubes, graphene and graphene nanoribbons) in pulsed magnetic fields up to 60 Tesla. Applying a magnetic field to such systems provides an efficient tool to investigate the band structure near the charge neutrality point. From the study of magnetoconductance in carbon nanotubes, we show how axial magnetic field as well as curvature, spin-orbint coupling, and Zeeman splitting modify the bandstructure of carbon nanotubes. Preliminary results on graphene and graphene nanoribbons are also reported, and technical issues to measure magnetoconductance of nanostructures in pulsed magnet facility are discussed.
