N doping of TiO 2(110) Photoemission and density-functional studies
(AIP Publishing, 2006-09)
The electronic properties of N-doped rutile TiO2(110) have been investigated using synchrotron-based photoemission and density-functional calculations. The doping via N+2 ion bombardment leads to the implantation of N atoms ...

Surface structure of cubic aluminum oxide
(American Institute of Physics Publising LLC, 1994)
Molecular-dynamics simulations using a Pauling type pairwise potential have been carried out in order to study the structure of the surface of γ-Al2O3. Starting from an ideal (100) face, a reconstruction process occurs in ...

Ab initio group model potentials including electron correlation effects
(AIP Publishing, 2000-10)
A method for determination of ab initio group model potentials, with the intention of describing the effects of a whole molecule or a chemical group within a density functional theory framework, is reported. The one-electron ...

Potassium and Water Coadsorption on TiO2(110): OH-Induced Anchoring of Potassium and the Generation of Single-Site Catalysts
(American Chemical Society, 2016)
Potassium deposition on TiO2(110) results in reduction of the substrate and formation of loosely bound potassium species that can move easily on the oxide surface to promote catalytic activity. The results of density ...

Interaction potentials from periodic density-functional theory calculations: Molecular-dynamics simulations of Au clusters deposited on the TiN (001) surface
(AIP Publishing, 2005-12)
Molecular-dynamics simulations of gold particles deposited on a TiN 001 surface have been accounted for through classical pair potentials describing the atom force field. The interaction between Ti–N, Ti–Ti, N–N, Au–Au, ...
