Phys. Rev. B 79, 073411 (2009) [3 pages]Simple connections in alkali adsorptionReceived 23 October 2008; published 25 February 2009 Stimulated by recent two-photon photoemission spectroscopy and density-functional theory studies by Petek and co-workers, a retrospective look at some fundamentals in the theory of ionic alkali adsorption on metal surfaces is presented that provides a simple correlation between free-atom ionization potentials, ionic size, adsorption heights, and spectroscopically observed alkali valence-electron binding energies. © 2009 The American Physical Society URL:
