Spin Symmetry of the Bilayer Graphene Groundstate
Frank Freitag, Markus Weiss, Romain Maurand +2
We show nonlinear transport experiments on clean, suspended bilayer graphene that reveal a gap in the density of states. Looking at the evolution of the gap in magnetic fields of d…
Homogeneity of Bilayer Graphene
Frank Freitag, Markus Weiss, Romain Maurand +2
We present non-linear transport measurements on suspended, current annealed bilayer graphene devices. Using a multi-terminal geometry we demonstrate that devices tend to be inhomog…
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…
