Non-monotonic Velocity Dependence of Atomic Friction — •Peter Reimann and Mykhaylo Evstigneev — Universität Bielefeld

We propose a theoretical model for friction force microscopy experiments with special emphasis on the realistic description of dissipation and inertia effects. Its main prediction is a non-monotonic dependence of the friction force upon the sliding velocity of the AFM-tip relative to an atomically flat surface.
