The friction has been measured as a function of the applied load, the direction of sliding and the degree of lubrication of the surface. It is found that the direction in which the cube surface has been polished affects both the magnitude and the symmetry of the friction. Our results imply, in contrast to earlier work, that the friction arises from a ratchet-type mechanism, and that polished diamond surfaces have unusual properties.
