Figure . Models of the symmetric 12-layer bulk supercells (top row) and of the similar size Agterminated and Pt-terminated symmetric slabs (here: for Ag1L, bottom row) used in reference for calculation of the surface energies etc. of different Ag/Pt(111) systems (light gray: Ag, olive: Pt) for systems with Ag films of 1, 2 or 3 layers thickness. The blue box shows the unit cell of the bulk. Cleaving along the planes indicated by the green solid and orange dashed lines in the bulk presentations generates the symmetric Ag-terminated slab and Pt-terminated slabs, respectively, from the periodic bulk, which are shown in the bottom row. In addition, we also show the asymmetric 6-layer slab (bottom row), which is normally used for such calculations. Adapted from Sakong et al. , published under a CC BY license.
