Abstract
Sliding friction between the tip of a friction force microscope and NaCl(10 0) was studied to deduce the velocity dependence of friction forces on the atomic scale. A logarithmic dependence of the mean friction force is reveal ed at low velocities. The experimental data are interpreted in terms of a m odified Tomlinson model which is based on reaction rate theory.
