Density-functional study of the adsorption of K on the Ag(111) surface
TL;DR: In this paper, fullpotential gradient corrected density-functional calculations of the adsorption of potassium on the Ag(111) surface have been performed, and the considered structures are $\mathrm{Ag}(111)(\sqrt{3}\ifmmode\times\else\texttimes\fi{}\squrt{3})R30\ifmmodes^\circ\else''textdegree\finishesuremath{-}K$ and

Effect of various adsorbates in dephasing and population decay of the Cu(1 0 0) image potential states
TL;DR: In this paper, a theoretical study of the electron dynamics in image potential states on Cu(1 − 0 − 0) surfaces with different types of adsorbates is presented, showing that scattering of an image state electron by an adsorbate induces inter-band and intra-band transitions leading respectively to the population decay and to the dephasing of the image state.

Theoretical approaches in adsorption: alkali adatom investigations
TL;DR: In this article, the dispersion, energy, effective mass, and width of surface (quantum well and image) states of alkali atoms on Cu(111) were determined by the embedding approach and compared with experiments.

Structure and chemical reactivity of the polar three-fold surfaces of GaPd: A density-functional study
Marian Krajčí,J. Hafner +1 more
TL;DR: The polar threefold surfaces of the GaPd compound crystallizing in the B20 (FeSi-type) structure (space group P2(1)3) have been investigated using density-functional methods and the prediction of Ga-terminated surfaces has been tested against the available experimental information.
Journal ArticleDOI
Evidences of alkali-induced softening of the oxygen-substrate bond.
TL;DR: The interaction of oxygen with alkalis (Na, K) on Ni(111) was studied by high-resolution electron energy loss spectroscopy, revealing a softening of the O-Ni bond and a strengthening of the alkali+O coadsorbed phase, in perfect agreement with recent theoretical calculations.

Ordering, metastability and phase transitions in two-dimensional systems
TL;DR: In this article, a new definition of order called topological order is proposed for two-dimensional systems in which no long-range order of the conventional type exists, and the possibility of a phase transition characterized by a change in the response of the system to an external perturbation is discussed in the context of a mean field type of approximation.

Adsorbate-substrate and adsorbate-adsorbate interactions of Na and K adlayers on Al(111)
TL;DR: The interesting result of the studied systems is that the difference in bond strengths between the ``normal'' and substitutional geometries is sufficiently large to kick out a surface Al atom.

Dislocation-mediated melting in two dimensions
TL;DR: In this paper, a theory of dislocation-mediated melting in two dimensions is described in detail, with an emphasis on results for triangular lattices on both smooth and periodic substrates, and the behavior of the specific heat, structure factor, and various elastic constants near these transitions is worked out.
