Projector augmented wave (PAW) method was employed to describe the electron-core interaction.17 Scalar relativistic PAW potentials and a converged 450 eV kinetic energy cutoff were used. An Au fcc lattice parameter from a previous study18 was employed (a, 4.170 Å, The (111) surface was modeled with four layers of atoms together with a 12-Å thick vacuum layer and a (4 x 2) rectangular lateral cell (along the 〈110〉 and 〈112〉 directions, A 2 x 2 x 1 Monkhorst-Pack grid of k-mesh was used to sample the Brillouin zone. The top two substrate layers were allowed to relax with the adsorbed thiolate layer. Au38(MT)x and AU 102(MT)44
