Abstract : We are using atomic force microscopy (AFM) to characterize the tribological properties of materials on an atomic scale. For these experiments we employ an ultrahigh vacuum instrument which measures the lateral and normal forces and current through a tip in contact with a surface which can be positioned with subAngstrom resolution. Friction of a sharp tip on a surface is investigated by profiling the surface, sliding the tip across the surface while measuring the normal and parallel forces and contact resistance, and profiling the surface after sliding. jg p. 5
