  We report ab initiocomputations with the Vienna ab Initio Simulation Package
(VASP) aimed at elucidating the adsorption mechanism of graphene-like
structures on (111) Pd, Pt, and Ni surfaces. To study the adsorption
properties, we simulate an already-formed graphene layer. We present a
comparative discussion of the graphene interactions with the three metals,
focusing on the very particular adsorption of graphene over Pd.
