摘要: 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 involves the use an intermediate mica template, itself is atomically smooth. demonstrate compatibility these model with surface force balance, opening up possibility measuring normal and lateral forces, including friction adhesion, between two sheets either contact or across liquid medium. conductivity allows forces to be measured while controlling potential. This new apparatus, expected importance future understanding applications lubrication electrochemical energy storage systems.
