Abstract
In a recent paper Krim and coworkers have observed that the friction force, acting on a thin physisorbed layer of N-2 sliding on a lead film, abruptly decreases by a factor of similar to 2 when the lead film is cooled below i ts superconductivity transition temperature. I discuss the possible mechani sms for the abruptness of the friction drop. (C) 2000 Elsevier Science Ltd. All rights reserved.
