Friction force microscopy (FFM) enables the unprecedented measurement of friction at the nanoscale. It is known that when FFM microcantilevers are dragged across surface, the nanometer tip executes stick-slip motions as the tip “plucks” individual atoms on the surface. Tomlinson’s model is usually used to explain these effects. In what follows we investigate the effects of tip compliance on the stick-slip motions in FFM. New results are predicted describing the transition from steady sliding to single and multiple atom stick-slip. Additionally, the effect of these different motions on the average frictional force is calculated.

Tribology—the science of friction, wear and lubrication—is of great importance for all technical applications where moving bodies are in contact. Nonetheless, little progress has been made in finding an exact atomistic description of friction since Amontons proposed his empirical macroscopic laws over three centuries ago. The advent of new experimental tools such as the friction force microscope, however, enabled the investigation of frictional forces occurring at well-defined contacts down to the atomic scale. This research field has been established as nanotribology. In the present article, we review our current understanding of the principles of atomic-scale friction based on recent experiments using friction force microscopy.
