Query: Atomic force microscope nanolithography of graphene: cuts, pseudo-cuts
  and tip current measurements   We investigate atomic force microscope nanolithography of single and bilayer
graphene. In situ tip current measurements show that cutting of graphene is not
current driven. Using a combination of transport measurements and scanning
electron microscopy we show that, while indentations accompanied by tip current
appear in the graphene lattice for a range of tip voltages, real cuts are
characterized by a strong reduction of the tip current above a threshold
voltage. The reliability and flexibility of the technique is demonstrated by
the fabrication, measurement, modification and re-measurement of graphene
nanodevices with resolution down to 15 nm.
