Abstract
The adsorption of CO on Ag(110) was recently explained using substrate mediated intermolecular interactions, but the underlying mechanism remains unclear. This study investigates both short- and long-range relaxation patterns for CO adsorption on Ag(110) surfaces and suggests that the relaxation mode can be explained by the interaction of heavy electrons on metal substrates in electron momentum space. The long-range relaxation mode for CO on Ag(110) involved a () commensurate phase, whereas the short-range relaxation involved an alleviation of Fermi surface nesting along the direction of the Ag(110) substrate. The symmetry broken ground state structure at high CO coverage from this work is consistent with the interpretation of available experimental data at low temperature.
