Electrons Meet at Step Edges

STM image of anatase (101) after oxygen exposure

2014-Apr-11

  • Excess electrons in TiO2 anatase are usually delocalized and behave as quasi-free particles. They are trapped, however, at defects such as steps. This is undesired in applications where a high electrical conductivity is essential, such as the Graetzel cell. On the other hand, electron localization can be beneficial in chemical applications. For example, oxygen prefers to adsorb close to surface steps. These effects are clearly seen in STM and NC-AFM images taken by Martin Setvin and other members of the surface physics group. The experimental results have been confirmed in theoretical calculations by Xianfeng Hao, Cesare Franchini, and Geoerg Kresse from Computational Materials Physics, University of Vienna.

The results were published in the journal Angewandte Chemie International Edition.

A Two-dimensional Electron Gas

Stefan, Bernhard and Zhiming at Bessy

2014-Mar-04

  • The SrTiO3(110) surface forms a reconstruction that consists of a monolayer TiO2, but in a special, rather unreactive - tetrahedrally coordinated - form. When oxygen vacancies are created in this layer, they move to the SrTiO3 interface, where the resulting excess electrons form a two-dimensional gas (2DEG). Zhiming Wang, Stefan Gerhold and Bernhard Stöger from the surface physics group have measured the electronic structure of this electron gas at the synchrotron Bessy in Berlin. (There they also took the happy photo at the right.) Different from other, known 2DEG's, this system shows a pronounced anisotropy that is depends on the doping level. The experimental results are complemented by theoretical calculations by Zhicheng Zhong and Karsten Held at the Institute of Solid State Physics, and Xianfeng Hao and Cesare Franchini, Computational Materials Physics, University of Vienna.

The results were published in the Proceedings of the National Academy of Sciences.

Vacancies Marching to the Top

STM image of oxygen on an anatase surface 2014-Sep-02

  • Anatase, a form of titanium dioxide (TiO2) is used in (photo)catalysis and many other applications. The interaction of oxygen molecules with this material is of central importance. How this happens on the atomic scale was investigated in experiments by Martin Setvin of the Surface Physics group and calculations by Annabella Selloni (Princeton University) and coworkers. It was found that O2 interacts with oxygen vacancies in the material, resulting in O2 (peroxo) molecules incorporated in the surface.
    These results were published in the prestigious journal Science.

The Dance of the Atoms

The Fe3O4 experts at the STM 2013-Jun-10

  • Metals such as gold or palladium are often used as catalysts to speed up certain chemical reactions. When the atoms ball together, most of them do not get into contact with the surrounding gas any more and the catalytic effect diminishes drastically. The mechanism of clustering is not well understood, however. In an article published in the prestigious journal Nature Materials, Gareth Parkinson and co-workers report on a detailed study of this issue; they have followed the fate of each surface atom and analyze how they are affected by different gas atmospheres. They find carbon monoxide to bind strongly to palladium atoms, helping them to move across the surface.

Single Gold Atoms

STM image of gold on magnetite

  • In the latest issue of Physical Review Letters [Phys. Rev. Lett. 108, 216103 (2012)], Zbyněk Novotný and colleagues describe the discovery of highly stable single gold atoms on a magnetite (Fe3O4) surface. This observation is expected to facilitate catalysis research: On the other substrates studied so far, gold atoms don't stay alone but easily form large clusters, which are considered less active catalysts than single atoms.
