Strain-induced Defect Superstructure on the SrTiO3(110) Surface
Zhiming Wang, Fengmiao Li, Sheng Meng +4
We report on a combined scanning tunneling microscopy and density functional theory calculation study of the SrTiO3(110)-(4 x 1) surface. It is found that antiphase domains are for…
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…
Coexistence of trapped and free excess electrons in SrTiO3
Xianfeng Hao, Zhiming Wang, Michael Schmid +2
The question whether excess electrons in SrTiO3 form free or trapped carriers is a crucial aspect for the electronic properties of this important material. This fundamental ambigui…
Water Adsorption at the Tetrahedral Titania Surface Layer of SrTiO(110)-(41)
Zhiming Wang, Xianfeng Hao, Stefan Gerhold +6
The interaction of water with oxide surfaces is of great interest for both fundamental science and applications. We present a combined theoretical [density functional theory (DFT)]…
Anisotropic two-dimensional electron gas at SrTiO3(110) protected by its native overlayer
Zhiming Wang, Zhicheng Zhong, Xianfeng Hao +8
Two dimensional electron gases (2DEGs) at a oxide heterostructures are attracting considerable attention, as these might substitute conventional semiconductors for novel electronic…
