The corresponding calculations of the surface energies of the Pd-terminated surfaces in Ag/Pd(111) systems revealed similar trends, with smaller differences to the Pd(111) surface energies. The only deviation with respect to the Ag/Pt(111) systems is again the Ag1L system, where for Ag/Pd(111) the difference with respect to Pd( ) is marginal and even negative, while for Ag/Pt(111) this was positive and biggest. The generally more Pd(111)-like surface energies of the Ag/Pd(111) systems indicate that the electronic properties of the Pd surface layer are less affected by the underlying Ag layers than this is the case for the Ag/Pt(111) systems. In particular, the long-range effects observed for the Ag1L system in the Ag/Pt111) case are absent. The resulting surface energies, which are listed in Table , closely resemble the values obtained for the Ag-terminated 12-layer slab via eq. ( ) (Table ). The small differences of at most 1 meV Å -2 are mainly due to the additional relaxation of the Ag layers upon cleaving, i.e., slight differences in the structure of the Ag layers compared to the Ag-terminated 12-layer system.
