Abstract

Sliding friction is a nonconservative force in which kinetic energy is dissipated via various phenomena. We used lateral force microscopy to measure the energy loss as a tip oscillates laterally above a surface with sub-Angstrom amplitudes. By terminating the tip with a single molecule, we ensure the tip ends in a single atom. We have reported that energy is dissipated as a CO molecule at the tip ...
