Friction between Carbon Nanotube and Graphite using Molecular Dynamics

The fundamental understanding of friction phenomena at atomic level is important in the area of micro-electro-mechanical system and so on. However, the existing knowledges of friction are all based on the Newton mechanics theory and experiments on macroscale. In this paper, the friction between CNT and graphite surface is studied by using classical molecular dynamics simulation. The result shows an anisotropic behavior of friction between two structures, and the symmetry of the nanotube can be characterized by the variation of potential energy as well.
