“…In many studies, continuum mechanics appears to provide an accurate description of the nanometre-scale contact area A and other contact properties [14,31,35,[47][48][49]. Key assumptions here are homogeneity, isotropy, linearity, and elasticity of the materials.…”

As the size of electronic and mechanical devices shrinks to the nanometre regime, performance begins to be dominated by surface forces. For example, friction, wear and adhesion are known to be central challenges in the design of reliable micro-and nano-electromechanical systems (MEMS/NEMS). Because of the complexity of the physical and chemical mechanisms underlying atomic-level tribology, it is still not possible to accurately and reliably predict the response when two surfaces come into contact at the nanoscale. Fundamental scientific studies are the means by which these insights may be gained. We review recent advances in the experimental, theoretical and computational studies of nanotribology. In particular, we focus on the latest developments in atomic force microscopy and molecular dynamics simulations and their application to the study of single-asperity contact.

“…UHV measurements in agreement with JKR theory were performed by Meyer et al on NaCl [39], Carpick et al on mica [40] and Polaczyk et al on Au (100) [41]. To extract the load dependence of friction Meyer et al applied an original 2D histogram technique, which allows investigation of the correlation between lateral and normal forces with improved statistics.…”

In this review, we present various results obtained by friction force microscopy in the last decade. Starting with material-specific contrast, commonly observed in friction force maps, we discuss how the load dependence of friction and the area of contact have been estimated and compared to elasticity theories. The features observed in a sliding process on the atomic scale can be interpreted within the Tomlinson model. An extension of the model, including thermal effects, predicts a smooth velocity dependence of friction, which recent experiments have confirmed. Other subjects like anisotropy of friction, role of environment, topographical effects, electronic friction and tip modifications are also discussed. The growing importance of molecular dynamics simulations in the study of tribological processes on the atomic scale is outlined.

“…1 The technique has been applied to the study of a wide range of systems, including: single crystals, 2 alkanethiols on gold, 3 conducting polymers, 4,5 polyurethanes 6 and biological surfaces. 7 Qualitative friction data may be obtained by subtracting the lateral force reverse trace from the forward trace.…”

A friction coefficient map of the surface of an immiscible polymer blend has been constructed using data obtained with the atomic force microscope. Spatially resolved friction coefficients, obtained from gradients of linear plots of frictional force versus applied load, were used to construct the map, with corresponding frictional forces being derived from lateral force data and the lateral spring constant. Values of the friction coefficient were confirmed using an Si 3 N 4 /Si 3 N 4 couple, for which literature values were available. Excellent agreement with the literature was observed through the use of this method.
