## Description

- description: "抄録\r\nSuperlubriity is one of the most interesting physical phenomena
    and leads drastic reduction of friction by controlling atomic structures of the
    interface. While the basic theoretical concept was proposed more than three decades
    ago, it remained challenging to observe the low-friction phenomena. Recent development
    of on-surface synthesis allows us to obtain nanocarbon materials whose structures
    can be atomically defined by employed precursor molecules. Here, we synthesized
    polyfluorne and graphene nanoribbon as sliding objects on atomically clean gold
    surfaces. We pulled the single fluorene oligomer 10–100 nm long from Au(111) with
    a tip of low-temperature atomic force microscopey. A combination of atomic force
    microscopy and calculations based on an extended Frenkel-Kontorova model revealed
    significant reduction of friction due to the incommensurability to the substrate.
    In the case of graphene nanoribbon, we found that the high stiffness keeps the
    incommensurability so that the superlubricity was observed.\r\n\r\n"
