Fig. 5

a, b Isosurface plots of \(\Delta \rho ({{\bf{r}}})=\pm \)0.007 e Å−3 for a single Ag or Au adatom, respectively. Charge accumulation is shown in red, depletion in blue. Indicated are the z height of the Ag surface atoms (grey, dashed) and of the adatom at z = 0 (solid). c, d Plots of the xy-integrated charge density difference Δρxy(z) for a single Ag or Au adatom (indicated as grey or yellow circle respectively).
