Abstract
Molecular dynamics and simple phenomenological simulations are used to mode l the friction between two ordered monolayers of alkane chains bound at the ir ends to rigid substrates. Results of calculations using these methods su ggest that the frictional properties at a sliding interface between the ord ered films are governed by two simplified potentials. One isa potential due to the lateral collective deformation of a film and the other is a corruga ted interfacial potential between films facing each other. These two potent ials are closely related to the nature of the films, i.e., their physical a nd chemical properties. In addition, the simplified models can be greatly e xtended to clarify the frictional behavior of other weakly interacting inte rfaces such as hydrogen-terminated diamond surfaces.
