21. A 3 × 3 surface unit cell was used for Au atoms and dimers II and III. Dimers I and IV were modeled with a 4 × 2 and a 5 × 2 surface unit cell, respectively. The vacuum region was 14.4 Å. The surface Brillouin zone was sampled with 24 k-points. A Fermi level smearing of 0.2 eV and a 202 eV plane wave cutoff were used.
