“…Experimental studies of alkalimetal neutralization on supported Ag and Au clusters were performed [24,25] in the quest of observation of quantum-size effects [27][28][29], and showed that alkali-metal neutralization proceeds much more efficiently on small clusters than on films or bulk metal surfaces. Recent theory has also addressed the case of electron transfer on ultrathin films [30,31] and the effect of quantization because of the finite thickness of the film. Again it was concluded that under certain conditions electron transfer processes could be strongly affected.…”

Li + ions with energies ranging from 0.3 to 2 keV are scattered from Au(110) and Pd(100) surfaces and from ultrathin Ag film grown on Au(111) in order to study electron transfer phenomena. We find that neutralization occurs quite efficiently and find an anomalous ion energy dependence of the neutral fraction for Au (110) and Pd(100) surfaces previously noted for Au(111). The dependence of the neutral fraction on the azimuthal angle of the Au(110) and Pd(100) surfaces is reported. In the case of Ag monolayer on Au (111), results are similar to the case of the Ag(111) surface. To understand the anomalous ion energy dependence, we present a theoretical study using density functional theory (DFT) and a linearized rate equation approach, which allows us to follow the Li charge state evolution for the (111) surfaces of Ag, Au, and Cu, and for the Ag-covered Au(111) surface.

“…An example of this is Li scattering from clean silicon, where the projectile ionization level couples to localized surface dangling bonds during scattering, rather than to delocalized bands [14]. Calculations have also suggested that ion scattering can detect confined states in a 2D thin film [17], but this has not yet been observed experimentally.…”
