Friction Modification by Shifting of Phonon Energy Dissipation in Solid Atoms

Numerous researchers have focused on the relation between kinetic friction and the surface properties of materials, such as their surface roughness and chemical state, because kinetic friction is the loss of kinetic energy at a sliding interface. Contrary to conventional wisdom, recent theory has pr...
