• materials revealed consistent results: Comparative adhesion force measurements of the (0001) basal planes and the (10−10) prism planes of highly oriented pyrolytic graphite (HOPG) and MoS2 also showed that the metallic state lowers the adhesion at the nanoscale [36].

• benchmark would be the flower-shaped Sb islands first manipulated by Ritter et al. on HOPG and MoS2 [9]. Possible discrepancies between theory and experiment concerning the direction of motion and angular speed of the islands could be related to the friction forces between island and substrate and even used
