The surface properties of SnO 2 (110)-4×1 and sputtered SnO 2 (110) were studied comparatively by resonant photoemission of the valence band states in a photon energy range of 60–130 eV. Resonating energetic levels could be observed on the 4×1 reconstructed surface and the resonance behavior could be switched off by sputter treatment. Additionally, the Sn4d core-levels were recorded...
First-principles calculations based on density-functional theory and pseudopotentials are used to study the energetics and structure of highly reduced SnO 2 (110) surfaces for which detailed experimental data have recently been reported. In the surfaces studied, all bridging oxygen ions are absent, and in-plane vacancies are present, the mean number of these vacancies per surface unit cell...
