Fig. 6: Cluster correction depends weakly on cluster size.
From: Adsorption energies on transition metal surfaces: towards an accurate and balanced description
Adsorption energy of CO on Cu clusters with increasing number of atoms using M06 (orange) and PBE+D3 (blue). The employed correction to the PBC adsorption energy, E(M06)-E(PBE+D3), is shown in gray. The variation of the adsorption energy vs. the number of atoms in the Cu clusters with M06 and PBE+D3 is similar, hence, the corrective term becomes almost constant. Lines are guides to the eye. Source data are provided as Source data file.
