    • note
    • The energetics obtained from the calculations with 8 layers are in agreement with those obtained with 16 layers. The thicker slab describes correctly the energy of the surface bands relative to the projected bulk band structure and is used for the computation and discussion of the electronic properties. The thinner slab is used to evaluate the relative energy of the several computed geometries.

    • The energetics and electronic structure of the most relevant surfaces were refined by using a finer grid of k points: six for the clean; twelve for 2H2H and 3H1H.

    • note
    • A full account of the reaction kinetics would require the computation of several geometries to describe the potential energy surface, and also the inclusion of zero-point energies in the energetics estimates. This is beyond the scope of this investigation, which is instead devoted to the electronic properties.

    • note
    • The other isostoichiometric surfaces investigated here, i.e., 4H and 3H1H, are semiconducting. We find metallic surfaces; only for different H contents.(3H and 2H1H, incompatible with the experimentally suggested hydrogenation amount), consistent with the basis of electron counting.
