    • [19,20] the diffusion TS energy correlates well with both the initial and the final state of the diffusion path, since both of these states and the TS itself are all similar to each other. In contrast, the correlation for the bond-breaking reaction on metals was far better between the TS and the FS, simply because the TS of the bond-breaking event was more like the final state (dissociation products) than the initial state.

    • note
    • We estimated the effect of relaxation of the top metal layer in our slabs for the case of N and O diffusion on Ru(0001), both with the equilibrium lattice constant. We observed that the calculated diffusion barrier moves closer to the experimental value, thereby reducing the total error to less than 0.1 eV. We expect that the effect of surface relaxation would be similar for other adsorbate/surface pairs, thus indicating that the trends that we have determined on static surfaces are valid.
