where the subscripts dep and sub denote slabs / bulk unit cells that are terminated by deposit or substrate surface layers, respectively. formation energies of the different Ag/Pt111) and Ag/Pd(111) systems (red: Ag, olive: Pt or Pd). The blue box shows the unit cell of the bulk. The slabs and thus the corresponding cleavage planes are indicated by solid green and dashed orange lines in the bulk presentations. In addition, we also show the asymmetric 6-layer slab (bottom row), which is normally used for such calculations (here: for the Ag1L system).
