Charge Trapping at the Step Edges of TiO2 Anatase (101)
Martin Setvin, Xianfeng Hao, Benjamin Daniel +7
A combination of Photoemission, Atomic Force and Scanning Tunneling Microscopy/Spectroscopy measurements shows that excess electrons in TiO2 anatase (101) surface are trapped at st…
Adsorption of water at the SrO surface of ruthenates
Daniel Halwidl, Bernhard Stöger, Wernfried Mayr-Schmölzer +9
Although perovskite oxides hold promise in applications ranging from solid oxide fuel cells to catalysts, their surface chemistry is poorly understood at the molecular level. Here…
Subsurface Cation Vacancy Stabilization of the Magnetite (001) Surface
R. Bliem, E. McDermott, P. Ferstl +9
Iron oxides play an increasingly prominent role in heterogeneous catalysis, hydrogen production, spintronics and drug delivery. The surface or material interface can be performance…
Adsorption of CO on the Fe3O4(001) Surface
Jan Hulva, Zdeněk Jakub, Zbynek Novotny +6
The interaction of CO with the Fe3O4(001)-(rt2xrt2)R45° surface was studied using temperature programmed desorption (TPD), scanning tunneling microscopy (STM) and x-ray photoelectr…
Point defects at cleaved SrRuO(001) surfaces
Bernhard Stöger, Marcel Hieckel, Florian Mittendorfer +10
The (001) surfaces of cleaved SrRuO and SrRuO samples were investigated using low-temperature scanning tunneling microscopy and density functional theory calcul…
Water Agglomerates on Fe3O4(001)
Matthias Meier, Jan Hulva, Zdenek Jakub +7
Determining the structure of water adsorbed on solid surfaces is a notoriously difficult task, and pushes the limits of experimental and theoretical techniques. Here, we follow the…
