Abstract
We have measured the quantum Hall activation gaps in bilayer graphene at filling factors ν = ± 4 and ν = ± 8 in high magnetic fields up to 30 T. We find that energy levels can be described by a 4-band relativistic hyperbolic dispersion. The Landau level width is found to contain a field independent background due to an intrinsic level broadening and a component which increases linearly with magnetic field.
