Query: Role of Van der Waals forces in graphene adsorption over Pd, Pt and Ni   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.
