The SnO 2 (1 0 1) surface can be prepared with a SnO 2 or SnO composition and consequently the surface Sn-atoms are either in a Sn(II) or Sn(IV) charge state. For a Sn(II) surface, Sn-5s derived surface states are identified by resonant, angle resolv

Photoemission and density functional theory studies show that water adsorbs dissociatively on the SnO 2 (1 0 1) surface in the presence of terminating oxygen atoms and molecularly if these surface oxygen atoms are removed. The different chemical surf

Complex surface reconstructions and surface oxides, in particular, often exhibit complicated atomic arrangements, which are difficult to resolve with traditional experimental methods, such as low energy electron diffraction (LEED), surface X-ray diff

Carbon adsorption on V(1 0 0) was studied by both experimental methods and density functional theory. At low carbon coverages of ΘC=0.18 ML and oxygen below the experimental detection limit, measured scanning tunneling microscopy (STM) images show b

The adsorption of 2.4 Langmuir oxygen on V(1 1 0) induces a c(6×2) reconstruction with an oxygen coverage of 0.5 ML. Its structure was determined using STM, quantitative LEED and ab initio density functional calculations in combination with molecula

SnO 2 (110) and (101) surfaces with eleven different kinds of terminations for each are systematically investigated by a first-principles projector augmented wave method. Surface energies are discussed as a function of temperature and oxygen partial

The oxygen coverage, structure, and thermodynamic stability of (0001) surfaces of ${\mathrm{Fe}}_{2}{\mathrm{O}}_{3}$ (hematite) as a function of temperature and oxygen pressure are investigated by ab initio density functional theory with the general
