Nanolithography and manipulation of graphene using an atomic force microscope
A. J. M. Giesbers, U. Zeitler, S. Neubeck +3
We use an atomic force microscope (AFM) to manipulate graphene films on a nanoscopic length scale. By means of local anodic oxidation with an AFM we are able to structure isolating…

Quantum-Hall activation gaps in graphene
A. J. M. Giesbers, U. Zeitler, M. I. Katsnelson +3
We have measured the quantum-Hall activation gaps in graphene at filling factors and for magnetic fields up to 32 T and temperatures from 4 K to 300 K. The gap ca…
