∆φ orient always screens the influence of ∆φ el by forming a compensating dipole of opposite sign, consistent with the physical picture of the electric double layer. Interestingly, as can be seen in the bottom panel in Figure , we find a much larger contribution of ∆φ orient to ∆φ AIMD for the stepped (211) surfaces, with values ranging from 0.8 to 1.2 eV, indicating that ∆φ orient is more of a facet dependent than a metal identity dependent property. Here, the geometry of the pronounced (211) step surface, already forms a surface dipole, which intensifies the orientational contribution. A higher ∆φ orient in stepped surfaces fits the trends reported for (110) vs. ( ), (100) surfaces in Refs . However, reported ∆φ orient in these studies have overall a negligible contribution which may be related to the simulation setup employed. According simulation cells consists of a metal-water-metal system instead of a metal-water-vacuum system used in this work.
