Phys. Rev. Lett. 66, 181–184 (1991)Nanotribology of a Kr monolayer: A quartz-crystal microbalance study of atomic-scale frictionReceived 15 October 1990; published in the issue dated 14 January 1991 A quartz-crystal microbalance has been utilized to probe sliding-friction effects in Kr monolayers undergoing solidification on Au and Ag surfaces. Solid layers are observed to be far more sensitive to surface morphology than liquids. The behavior of liquid layers is consistent with a frictional force whose magnitude is a nonlinear function of the sliding velocity. © 1991 The American Physical Society URL:
