Journal ArticleDOI
Velocity Dependence of Atomic Friction
Enrico Gnecco,Roland Bennewitz,T. Gyalog,Ch. Loppacher,M. Bammerlin,Ernst Meyer,H.-J. Güntherodt +6 more
TL;DR: Sliding friction between the tip of a friction force microscope and NaCl(100) was studied to deduce the velocity dependence of friction forces on the atomic scale and a logarithmic dependence of the mean friction force is revealed at low velocities.
Journal ArticleDOI
Friction and Dissipation in Epitaxial Graphene Films
Tobin Filleter,J. L. McChesney,Aaron Bostwick,Eli Rotenberg,Konstantin V. Emtsev,Thomas Seyller,Karsten Horn,Roland Bennewitz,Roland Bennewitz +8 more
TL;DR: The friction contrast between single and bilayer graphene arises from a dramatic difference in electron-phonon coupling, which is discovered by means of angle-resolved photoemission spectroscopy.
Journal ArticleDOI
Transition from stick-slip to continuous sliding in atomic friction: entering a new regime of ultralow friction.
TL;DR: A transition from stick-slip to continuous sliding is observed for atomically modulated friction by means of a friction force microscope and the results are compared to a recently discussed concept called superlubricity.
Journal ArticleDOI
Interaction potential and hopping dynamics governing sliding friction
TL;DR: The friction force on a nanometer-sized tip sliding on a surface is related to the thermally activated hopping of the contact atoms on an effective atomic interaction potential and the hopping attempt frequency falls in the range of mechanical eigenfrequencies of the probing tip in contact with the surface.
