formation than working in air. Conversely, for graphene on SiC the EB process is not successful under vacuum. Finally, the EB is possible with turbostratic graphene discs only after the creation of a constriction in the sample using lithographic patterning.

optimal working conditions for the different types of device. We believe that these results will contribute to the realization of reliable graphenebasedelectrodes for molecular electronics and spintronics.
Experimental
Few-layer graphene flakes were deposited by the standard “scotch tape” mechanical
