Stoichiometry-driven switching between surface reconstructions on SrTiO(001)
Stefan Gerhold, Zhiming Wang, Michael Schmid +1
Controlling the surface structure on the atomic scale is a major difficulty for most transition metal oxides; this is especially true for the ternary perovskites. The influence of…
Vacancy clusters at domain boundaries and band bending at the SrTiO(110) surface
Zhiming Wang, Xianfeng Hao, Stefan Gerhold +3
Antiphase domain boundaries (APDBs) in the ()() reconstructions of the SrTiO(110) surface were studied with scanning tunneling microscopy, x-ray photoemissio…
Stabilizing Single Ni adatoms on a Two-dimensional Porous Titania Overlayer at the SrTiO(110) Surface
Zhiming Wang, Xianfeng Hao, Stefan Gerhold +7
Nickel vapor-deposited on the SrTiO(110) surface was studied using scanning tunneling microscopy, photoemission spectroscopy (PES), and density functional theory calculations.…
High chemical activity of a perovskite surface: reaction of CO with SrRuO
Bernhard Stöger, Marcel Hieckel, Florian Mittendorfer +7
Adsorption of CO at the SrRuO(001) surface was studied with low-temperature scanning tunneling microscopy (STM) and density functional theory. In situ cleaved single cr…
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…
Transition from reconstruction towards thin film on the (110) surface of strontium titanate
Z. Wang, A. Loon, A. Subramanian +12
The surfaces of metal oxides often are reconstructed with a geometry and composition that is considerably different from a simple termination of the bulk. Such structures can also…
