Abstract
We investigated the load dependence of two-dimensional atomic-scale fr iction between a MoS2 surface and a Si3N4 tip We found that the amplit ude of the frictional force hysteresis is determined by the effective adhesive radius itself. Besides, we observed nearly zero kinetic frict ional force at the normal load of 2.3 X 10(-8) N. The load dependence of the effective adhesive radius suggests that the appearance of the n egative frictional force correlates clearly with the load dependence.
