TL;DR: In this paper, it was shown that the activation energies for the adsorbates increased in the order Au, Pt, Ir, and P, with the differences in adatom size having little effect.

TL;DR: In this article, the surface segregation of Cu-Ni and Cu-Pt alloys is studied under equilibrium conditions and the influences of parameters such as relaxation, crystal face, atomic size and double-layer formation are discussed.

TL;DR: In this article, low coverages of vacuum deposited palladium on amorphous silica films have been examined with electron microscopy and photoelectron spectroscopy, and changes in the Pd valence band as a function of increasing particle size could be clearly followed in UPS.

TL;DR: In this paper, surface compositional changes were observed for TiO2 single crystal electrodes used for photo-electrolysis of water, and they were compared with a variety of titanium, titanium oxide and titanium hydride standard materials.

TL;DR: In this paper, a laser heating technique for studying fast surface processes has been applied in an initial study to the thermal desorption of D 2 from a polycrystalline tungsten sample.

TL;DR: The phase diagram for a lattice-gas model of physical adsorption on a homogeneous substrate has been calculated in a mean-field approximation as mentioned in this paper, and the first-order phase transitions corresponding to the addition of successive layers terminate in individual critical points as the temperature increases.

TL;DR: In this article, the authors used a standard bulk model of interatomic force constants for the pairing model of 2 × 1 reconstruction on the (100) surface of C, Si and Ge.

TL;DR: In this article, the authors presented a simple model to calculate the charge exchange probability for ions scattering from solid surfaces, including interactions with both broad band delocalized electrons and with localized core electrons within an Anderson type Hamiltonian with time dependent parameters.

TL;DR: In this paper, several models are developed for desorption rates which proceed through precursor intermediate states, including associative and dissociative chemisorption with one and two types of precursor states.

TL;DR: In this paper, the adsorption of oxygen on the Pt(S)-[12(111) × (111) surface has been studied by Auger electron spectroscopy, low energy electron diffraction and thermal desorption.

TL;DR: In this paper, two independent methods have been devised to analyse the process of surface diffusion at a planar surface using Monte Carlo simulation and order-disorder theory in the quasi-chemical approximation to provide an analytical expression for the influence of lateral interactions on surface diffusion profiles.
