Comparison of simulated tip–surface and dimer potential energy curves with experimentally derived curves (the same experimental data as in Fig. 3e) for each rare gas atom pair. The z-position of the experimental curves has been normalized with respect to the simulated Xe–Kr tip–surface curve. The curves were fitted with polynomial functions. Inset: atomic snapshot of the simulated tip–surface system.
