A single layer of graphene on steel\nsurfaces causes a change in the near-surface structure of the model lubricant\nhexadecane. Hexadecane adsorbs in an ordered layer aligned straight molecules,\nand this layer is stable under scanning in contact with the tip of an atomic\nforce microscope, while no such layer is observed on the steel substrate.\nGraphene and hexadecane layer reduce friction at the nanoscale by a factor of\nthree compared to the bare steel in hexadecane. *<\/p>\n\n\n\n
All AFM measurements described in this letter were performed using a NANOSENSORS\u2122 PointProbe\u00ae Plus<\/a> PPP-CONTR<\/a> AFM probe at room temperature with a home-built fluid cell where the cantilever was fully immersed in hexadecane.*<\/p>\n\n\n\n *G.

High-resolution lateral force maps recorded in hexadecane with a normal force of 3 nN. (a) On graphene, the adsorbed hexadecane molecules arrange in form of lamellae with a width of 2.1 nm. The cross-section was taken along the line indicated. The schematic depiction of the orientation of one hexadecane molecule is informed by the results in [21]. (b) On the steel substrate, an irregular stick-slip pattern with a characteristic slip length of about 1 nm is observed. The two cross-sections are taken the along the lines indicated in the respective color. <\/figcaption><\/figure>\n\n\n\n
