Magnetically driven atomic force microscope for precision interfacial force measurements

Wenhai Han, Stuart Lindsay

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Force spectroscopy of the MAC Mode atomic mode microscope (AFM) has been used to probe ordered liquid molecules of OMCTS and mesitylene at the graphite surface with sub-angstrom vertical distance resolution. The interaction force obtained from the spectra showed details well under 1 pN, more than one order of magnitude better than what a conventional contact mode AFM can resolve. Elastic compliance at the center of each layer was found to exponentially decrease versus the number of layers.
