The Adsorption of Atomic Nitrogen on Ru(0001): Geometry and Energetics
S. Schwegmann, A. P. Seitsonen, H. Dietrich +4
The local adsorption geometries of the (2x2)-N and the (sqrt(3)x sqrt(3))R30^o -N phases on the Ru(0001) surface are determined by analyzing low-energy electron diffraction (LEED)…
Ab initio study of step formation and self-diffusion on Ag(100)

Study of CO Oxidation over Ru(0001) at High Gas Pressures
C. Stampfl, M. Scheffler
Experiments performed at high gas partial pressures have demonstrated that the kinetics of the CO oxidation reaction at Ru(0001) is different and somewhat anomalous compared to tha…
Theory of Alkali Induced Reconstruction of the Cu(100) Surface
S. Quassowski, K. Hermann
LEED experiments show that Li adsorbed at Cu(100) surfaces at room temperature induces a (2x1) missing row substrate reconstruction while adsorption at lower temperatures, T=180 K,…
A Model for the Thermal Expansion of Ag(111) and other Metal Surfaces
Shobhana Narasimhan, Matthias Scheffler
We develop a model to study the thermal expansion of surfaces, wherein phonon frequencies are obtained from ab initio total energy calculations. Anharmonic effects are treated exac…
Diffusivity of Ga and Al adatoms on GaAs(001)
A. Kley, M. Scheffler
The diffusivity of Ga and Al adatoms on the (2x4) reconstructed GaAs(001) surface are evaluated using detailed ab initio total energy calculations of the potential energy surface t…
Steering and isotope effects in the dissociative adsorption of H_2/Pd(100)
Axel Gross, Matthias Scheffler
The interaction of hydrogen with many transition metal surfaces is characterized by a coexistence of activated with non-activated paths to adsorption with a broad distribution of b…
Strained tetragonal states and Bain paths in metals
P. Alippi, P. M. Marcus, M. Scheffler
Paths of tetragonal states between two phases of a material, such as bcc and fcc, are called Bain paths. Two simple Bain paths can be defined in terms of special imposed stresses,…
Role of defects and impurities in doping of GaN
J. Neugebauer, C. G. Van de Walle
We have calculated formation energies and position of the defect levels for all native defects and for a variety of donor and acceptor impurities employing first-principles total-e…

The formation of chemisorbed O-phases on Ru(0001) by exposure to O_2 at low pressures is apparently limited to coverages Theta <= 0.5. Using low-energy electron diffraction and den…
