Molecular Dynamics Simulation of Energy Dissipation Process in Atomic-Scale Stick-Slip Phenomenon

A molecular dynamics simulation is performed to clarify the energy dissipation process in the atomic-scale friction, particularly with the two-dimensional atomic-scale stick-slip phenomenon as observed in the friction experiment by AFM/FFM. In the present simulation, a well defined Cu{1 0 0} surface...
