Fabrication and tribological properties of nanogrids on CVD-grown graphene.
We have used atomic force microscopy (AFM) combined with an external sourcemeter to make patterns on CVD-grown graphene, and regular nanogrids have been fabricated on graphene by AFM tip-induced local oxidation. The friction and adhesion properties of graphene with the nanogrids have been characterized by the lateral mode of AFM and the results show that the friction force on the borders of nanogrid is higher than that on the normal area of graphene, yet the adhesion force on the nanogrids decrease slightly due to the change of surface roughness.
