Superlubricity on the way from laboratory science to application

Superlubricity is a state of vanishing friction, where single atom energy barriers are efficiently reduced by collective interactions of larger ensembles of interface atoms. By applying lateral nanomanipulation techniques to NaCl-nanoparticles on HOPG, fundamental characteristics of this new friction state have been explored. The recent results reveal new insights into the scaling laws of superlubricity for polycrystalline interfaces. At the same time, the results hint at new strategies to transfer this technologically promising friction state from clean vacuum conditions to application under ambient conditions.
