a Measured total dipole moments P⊥ of Ag adatom chains and clusters (dark yellow circles and grey squares), and Au adatom chains (teal circles). The uncertainty interval of our P⊥ values can be assessed since we have fabricated and measured several Ag structures with 1 ≤ N ≤ 4, the P⊥ values of which largely overlap in the plot. b Dipole moment per atom P⊥/N, for the data in (a). The crosses and dotted lines (brown and dark green) mark the values obtained from our DFT calculations for N = 1, 2, ∞, the dashed dark yellow and teal lines mark the respective asymptotic limits N = ∞ for the experimental data as obtained from the linear fits in (a).
