Abstract

We employ a quantum mechanical model to describe nonclassical effects in the optical response of crystalline noble metal films, demonstrating that such effects can be contained in quantum surface-response functions known as Feibelman d-parameters. In particular, we extract d-parameters characterizing the surface response of (111) and (100) crystallographic facets of silver, gold, and copper, and apply them in simple optical response calculations to capture important features emerging due to electron spill-in/out, surface states, and the projected electronic gap emerging from corrugation of the confinement potential by stacked atomic planes.
