TY - JOUR A1 - Osterloh, Niklas A1 - Silber, David A1 - Traeger, Franziska A1 - Wöll, Christof T1 - Water adsorption on r-TiO2(110): Presence of a well-defined (1 × 1)-structure as evidenced by He-atom scattering T2 - physica status solidi (pss) N2 - The adsorption of water on r-TiO2(110) has been investigated with thermal desorption spectroscopy (TDS) and helium atom scattering. Conventional TDS using a mass spectrometer and He-TDS monitoring reflected He beam intensity consistently show the existence of a structurally well-defined monolayer as well as a highly ordered second layer of water and a disordered multilayer phase. He diffraction patterns recorded along the high symmetry [001], equation image, and equation image directions reveal a well-ordered superstructure with (1x1) symmetry, providing strong evidence for the absence of a partially dissociated monolayer on the perfect parts of the substrate. No changes in the diffraction patterns are observed after irradiation with UV-light.
