Abstract Coverage-dependent core level binding energies of Na adsorbed on both Cu(111) and Ni(111) surfaces have been measured by angle-integrated photoemission spectroscopy. For increasing Na coverage, the core level binding energies of the Na 2p and 2s levels decreased by 0.93 and 0.81 eV for Cu(111), and 1.1 and 0.95 eV for Ni(111), respectively, up to completion of the first monolayer. The qualitative behavior of the 2p and 2s level was similar for both systems. A local density functional… CONTINUE READING
