| Abstract: | A sudden drop in mechanical friction between an adsorbed nitrogen monolayer and a lead substrate occurs when the lead passes through the superconducting transition temperature. We attribute this effect to a sudden drop at the superconducting transition temperature of the substrate Ohmic heating. The Ohmic heating is due to the electronic screening current that results from the sliding adsorbed film. |
