Tartalmi leírás:
We report a method for transferring graphene, grown
by chemical vapor deposition, which produces ultraflat graphene
surfaces (root-mean-square roughness of 0.19 nm) free from
polymer residues over macroscopic areas (>1 cm2). The critical
step in preparing such surfaces involves the use of an intermediate
mica template, which itself is atomically smooth. We demonstrate
the compatibility of these model surfaces with the surface force
balance, opening up the possibility of measuring normal and lateral
forces, including friction and adhesion, between two graphene sheets
either in contact or across a liquid medium. The conductivity of the
graphene surfaces allows forces to be measured while controlling the
surface potential. This new apparatus, the graphene surface force
balance, is expected to be of importance to the future understanding
of graphene in applications from lubrication to electrochemical energy storage systems.
