Abstract
In this work, the mechanical properties of C(60) molecules adsorbed on Cu(111) are measured by tuning-fork-based noncontact atomic force microscopy (nc-AFM) and spectroscopy at cryogenic conditions. Site-specific tip-sample force variations are detected above the buckyball structure. Moreover, high-resolution images obtained by nc-AFM show the chemical structure of this molecule and describes unambiguously its orientations on the surface.
