Abstract
This paper reviews simple theoretical models and recent experimental advances concerned with frictional processes at the atomic scale. Two simple models for wearless interfacial friction are discussed, the independent oscillator (IO) model, and the Frenkel-Kontorova model. The IO model is compared with molecular dynamics calculations between films of close-packed alkane molecules. Atomic force microscope studies of friction are discussed, and the role of other tip-based proximal probe techniques in understanding tribological processes is reviewed.
