A. Widom et J. Krim, SPREADING DIFFUSION AND ITS RELATION TO SLIDING FRICTION IN MOLECULARLY THIN ADSORBED FILMS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 49(5), 1994, pp. 4154-4156
The Einstein relations between frictional transport and diffusion coef
ficients are applied to the special case of a molecularly thin adsorbe
d film in order to demonstrate the equivalence between film-substrate
sliding friction and the collective spreading diffusion properties of
the film on its substrate.
