Abstract

 

Nanoscale investigations of friction have demonstrated that superlubricity is possible.
The aim is to explore how these nano-scale concepts can be transferred to the
macroscale. The main focus will be on onion-like fullerene structures, which are
formed by tribomechanical processes of hydrogenated carbon films. We will determine
the macroscopic friction coefficients and characterize the samples with surface
sensitive techniques as well as high resolution transmission electron microscopy. In
order to achieve a fundamental understanding of the microscopic mechanisms of
onion-like fullerene films, we will transfer individual onion-like fullerenes and explore
rotational/translational degrees of freedom on the microscopic scale and test the
suitability for superlubric conditions.
