For analysis of kinetic friction between solids on the atomic scale, a solid surface model that consists of a coupled oscillator with a semi-infinite thickness is developed by Green's function scheme. The approach shows that friction depends on not only surface atoms and their interaction, but also bulk atoms in a solid. Energy transfer from kinetic energy of a sliding solid to low-frequency lattice vibration occurs in the presence of bulk atoms, and energy dissipation into the bulk system leads to friction.
