Nanofriction: The Observation of Elastic Plowing



Z C. Ying, Stephen M. Hsu


Accurate friction measurement at nanoscale is critical in reliable device design. Literature papers have reported different friction values for the same materials pair when different instruments and tip sizes were used. We have conducted a series of experiments with the aim to delineate the effects of tip sizes and shapes on friction as a function of load and found that friction force values under elastic deformation regime for various tips can be unified when plotted against the tip cross-sectional area in the direction of sliding. This observation implies a volumetric dependence of friction that has not been reported before in the elastic regime.
