Arranging Molecules in Two or Three Dimensions

Molecules on Au(111) 2015-February

  • Charged molecules can self-organise on a gold surface to form highly structured motifs. In an effort led by Stijn Mertens, it was demonstrated that, under electrochemical conditions, this principle can be extended from flat structures into the third dimension. The results have been published in the journals Angewandte Chemie and Chemical Communications.

Superresolution Microscopy of Mitochondria

Gerhard Schütz at the Laser of the Superresolution Microscope 2014-December-22

  • Mitochondria are essential for our cells, they produce the energy carrier ATP. Unfortunately, mitochondria are too small for scrutiny by conventional light microscopy. Using superresolution microscopy techniques, the IAP biophysics group has determined where the relevant proteins are located in mitochondria, which provides important insights into how mitochondria work. These results are published in the prestigious journal Proceedings of the National Academy of Sciences of the United States of America (PNAS).

Surface Structure of an Iron Oxide Unraveled

Magnetite crystal structure 2014-December-05

  • A team around Gareth Parkinson of the Surface Physics group has solved a long-standing mystery: No one could explain why the magnetite Fe3O4(001) surface behaves differently than all other oxides. It turned out that this surface has a very peculiar crystal structure, which requires a new way of thinking about oxide surfaces in general. The results have been published in the prestigious journal Science.

Nanoantennas from Femtosecond Laser Pulses

nano-antenna 2014-June-2

  • Wolfgang Husinsky and his co-workers have demonstrated for the first time that an array of nanoantennas (central nanotips inside sub-micrometer pits) on an aluminum surface, fabricated using a specific double-pulse femtosecond laser irradiation scheme, results in a 28-fold enhancement of the non-linear (three-photon) electron photoemission yield. The results are reported in the latest issue of Laser Physics Letters.

Stop! In the Name of Carbon

HCI-surface interaction 2014-April-18

  • A bullet fired through a block of wood will slow down. In a similar way, ions are decelerated when they pass through a solid material: the thicker the material, the larger the energy loss will be. However, this picture breaks down in ultra-thin target materials, which only consist of a few layers of atoms. This was recently demonstrated by Fritz Aumayr and his group in collaboration with the Helmholtzzentrum Dresden-Rossendorf. The results are reported in the latest issue of Physical Review Letters

A Two-dimensional Electron Gas

Stefan, Bernhard and Zhiming at Bessy


  • 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 2013-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.
