Interfacial Charge Density and Its Connection to Adhesion and Frictional Forces
Interfacial Charge Density and Its Connection to Adhesion and Frictional Forces
We derive a connection between the intrinsic tribological properties and the electronic properties of a solid interface. In particular, we show that the adhesion and frictional forces are dictated by the electronic charge redistribution occurring due to the relative displacements of the two surfaces in contact. We define a figure …
