Abstract

In this study we investigated the tribological properties of C60 thin films which were deposited onto NaCl(001). The used scanning force microscope (SFM) allows simultaneous measurements of normal and lateral forces under ultrahigh vacuum (UHV) conditions. The friction coefficient at the interface between the probing tip (oxidized Si) and the C60-islands is found to be 0.15. By increasing the normal force from 2 to 10 nN, the lateral force on impact with the step edge is sufficient to move the C60 island as an entity in a controlled way and without destroying them. From the analysis of the lateral force signals during the shear event, dissipation and cohesive energies of C60 can be derived. The presented results have impact for the field of nanotechnology, e.g. as a nanosled-type transport system.
