This volume in the Springer Series on Surface Sciences presents a recent account of advances in the ever-broadening field of electron-and photon-stimulated sur face processes. As in previous volumes, these advances are presented as the proceedings

First principles density-functional slab calculations are used to study 5 {angstrom} (two O-layer) Al{sub 2}O{sub 3} films on Ru(0001) and Al(111). Using larger unit cells than in a recent study, it is found that the lowest energy stable film has an

Atom-by-atom and concerted hopping of ad-dimers on the open (100) surface of fcc metals are studied by means of density-functional calculations. The adatom interaction is relatively short ranged, and beyond next-nearest neighbors ad-dimers are effect

Density-functional calculations reveal that isolated F s and V s surface vacancies on MgO(100) ionize single Pt atoms, roughly tripling their adsorption energy. This trapping inhibits Pt atoms from binding to other Pt atoms, resulting in a negative a

First-principles density-functional calculations are used to study metal adsorption (Li, K, Y, Nb, Ru, Pd, Pt, Cu, Ag, Au, and Al at 1/3-4 monolayer coverages) atop 5 ~ A1203 films on Al(Ill). The oxide-metal bond is ionic at Iow coverages but, with

A first-principles density-functional local density approximation study of substitutional La, using 120-atom supercells of $\ensuremath{\alpha}\ensuremath{-}\mathrm{Al}{}_{2}{\mathrm{O}}_{3}$, shows that La assumes a highly displaced position, moving

We examine the effects of an electronegative coadsorbate on the electron-stimulated-desorption (ESD) yield and desorbate energies (translational and internal) of a chemisorbed molecule. Specifically, we use laser resonance-ionization spectroscopy to

Using laser resonance-enhanced ionisation spectroscopy, we have studied electron (6–350 eV) stimulated dissociation of NO2 coadsorbed with up to 0.75 monolayer of atomic O on Pt(111). Several dramatic effects on NO2 dissociation occur due to the pr

First principles density functional calculations are used to study the structure and properties of ultrathin films of alumina on Al(111) and Ru(0001) substrates. We focus on ∼5 Å two O-layer films, naturally produced by oxidizing NiAl, Ni3Al, and
