Abstract

Friction force microscopy is implemented in ultrahigh vacuum conditions, Atomic-scale friction is observed on clean surfaces. The onset of atomic-scale stick-slip is observed and discussed in relation to the plucking model. Comparative measurements of AgBr(001) versus NaCl(001) and C-60 versus NaCl(001) demonstrate the material-specific contrast of friction. Contrast mechanisms are discussed in relation to these experiments. The role of the chemical nature of the tip is exemplified for the case of Si(111) 7 x 7, where wearless sliding is achieved with a PTFE-coated probing tip.
