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
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.
Journal ArticleDOI
Superlubricity of graphene nanoribbons on gold surfaces.
Shigeki Kawai,Andrea Benassi,Andrea Benassi,Enrico Gnecco,Hajo Söde,Rémy Pawlak,Xinliang Feng,Klaus Müllen,Daniele Passerone,Carlo A. Pignedoli,Pascal Ruffieux,Roman Fasel,Roman Fasel,Ernst Meyer +13 more
TL;DR: The atomically well-defined contact allows us to trace the origin of superlubricity, unraveling the role played by ribbon size and elasticity, as well as by surface reconstruction, and pave the way to the scale-up of superLubricity and thus to the realization of frictionless coatings.
Journal ArticleDOI
Atomic-Scale Control of Friction by Actuation of Nanometer-Sized Contacts
Anisoara Socoliuc,Enrico Gnecco,Sabine Maier,Oliver Pfeiffer,Alexis Baratoff,Roland Bennewitz,Ernst Meyer +6 more
TL;DR: The technique represents a valuable way to minimize energy dissipation in nanocontacts by exciting the mechanical resonances of the sliding system perpendicular to the contact plane to reduce friction below 10 piconewtons.
