A diary of some remarkable events in the Surface Physics group…
- Jong Il Jake Choi successfully defends his PhD thesis entitled “Studies of Zirconia Surfaces On the Atomic Scale”. Congratulations, Dr. Choi!
- Our comprehensive study of metal adatoms and clusters on ultrathin zirconia films is accepted for publication in the Journal of Physics C.
- First nice day of the year. Following our tradition we venture out to Naschmarkt, where we greet the season with a kebap lunch.
- Giada Franceschi, a physics student from Polimi in Milano joins us for a 6 months. She is working on her Masters thesis, performing growth and surface experiments using our Laser MBE.
- The surface physics group shows a strong presence at this year's Spring Meeting of the German Physics Society in Regensburg, Germany. Most prominently, Martin Setvin is selected as a finalist for the Gerhard Ertl Young Investigator Award, and gives a brilliant talk summarizing his research on fundamental photocatalytic processes. Well done, Martin!
- The first paper reporting results from our Laser MBE setup will appear soon: Stefan Gerhold et al., “Adjusting Island Density and Morphology of the SrTiO3(110)-(4×1) Surface: Pulsed Laser Deposition Combined with Scanning Tunneling Microscopy” shows what happens during the very initial stages of homoepitaxial growth. Our new toy works well and more exciting results are in the works. Stay posted!
- The manuscript “Fe3O4(110)-(1×3) Revisited: Periodic (111) Nano-Facets” by Gareth Parkinson et al. will appear as a Letter in the journal Surface Science. We celebrate with beer and 'burgers.
- We happily report that four manuscripts have been accepted recently. Each paper has resulted from an extended collaboration. The one entitled “Interplay between steps and oxygen vacancies on curved TiO2(110)” by L. Alejandro Miccio et al., will appear in the journal Nanoletters. Former Post-doc Zhiming Wang is the first author of “Itinerant polaronic carriers in a SrTiO3-based two-dimensional electron gas”, to appear in Nature Materials, and of “Transition from Tetrahedral to Octahedral Coordination for High TiO2 Coverages of the (110) Surface of Strontium Titanate”, which is accepted for publication in Nanoletters. The group of Juan de la Figuera was leading the collaboration on “Co on Fe3O4(001): Towards precise control of surface properties”, published in The Journal of Chemical Physics. Congratulations to all co-authors!
- Our excellent technicians help Michael with realizing his ingenious ideas. We warmly thank Rainer, Martin, Herbert, and Marie, and we eat lots of cake.
- Dr. Zbynek Novotny is one of two recipients of this year's Loschmidt Prize. This prize is awarded annually by the Austrian Chemical Physics Society for an outstanding PhD thesis.

- Our research on strontium ruthenate surfaces shows how water dissociates and strips off one hydrogen atom upon adsorption. Although the hydrogen atom and the remaining OH group are physically separated, the pieces continue to interact through a weak hydrogen bond. This interaction leads to an interesting dynamic behavior, where the OH group circles the stripped off hydrogen atom. The result were published in Nature Materials. Click twice on the gif file on the right and watch the water dance.
- The European Academy of Sciences established the Blaise Pascal Medal in 2003 to recognize an outstanding and demonstrated personal contribution to science and technology and the promotion of excellence in research and education. Up to six medals may be awarded in any one year. This year Ulrike Diebold was honored with the Blaise Pascal Metal in Materials Science.
- Our “magnetite subgroup” around Gareth Parkinson and Roland Bliem, with the help of our guest Jessi van der Hoeven from Utrecht, could nicely show how a prototype catalytic reaction works. They find that CO oxidation on their model catalyst, tiny platinum clusters on magnetite, eats the oxygen from the magnetite support, and platinum helps to oxidize the support again. They could also investigate in detail what happens if hydrogen is oxidized with the help of the catalyst. These results provide the groundwork to improve catalysts and got published in Angewandte Chemie International Edition.
- Many of us are swarming out this month, to learn new things and to report on our research results. Roland Bliem, Michele Riva, Daniel Halwidl, Michael Schmid, and Peter Varga attend this year's ECOSS in Barcelona. Margareta Wagner, Martin Setvin, Jake Choi, Ulrike Diebold, Stefan Gerhold, Jonas Gloss, Peter Lackner report at the joint meeting of the Austrian and Swiss Physics Societies. Gareth Parkinson lectures at the GRC Summer School on Characterization of Metal Oxides near Berlin. Oscar Gamba gives a talk at a catalysis conference in Colombia, and Martin Setvin travels to the Non-Contact AFM conference in France.
- Roland Bliem attends the Suncat Summer School at Stanford and wins a best poster award. Congratulations!
- This week, no less than four papers were accepted for publication in various journals. The picture shows our first authors: Stefan Gerhold's paper on NiO on SrTiO3(110) was accepted in J. Phys. Chem. C, and so was Oscar's paper on formic acid on Fe3O4. Roland's work on the adsorption and incorporation of transition metals in magnetite was accepted in Phys. Rev. B. Another paper, on imaging TiO2(110) in aqueous solution with STM, spearheaded our collaborators in Rome, was accepted in Advanced Materials Interfaces. Also, the weather has been really hot. Time for some beer!
- Three students from Brno have been with us since February. Adam Zavodny took many interesting STM images of single adatoms on Fe3O4, Zdenek Jakub helped with our electrochemistry setups, and Michal Horky grew fcc-stabilized Fe films. It has been a pleasure and privilege working with them.
- This year, we hike in the Wienerwald. We conquer the Anninger, stop at Ruine Mödling, and relax in Peter Varga's house in Maria Enzersdorf with lots of cold drinks.
- Prof. Bilge Yildiz from the Departments of Nuclear Science & Engineering and Materials Science and Engineering at MIT is spending her sabbatical year in our group.

The prize money will enable him to pursue research on single-atom catalysis during the next six years. We have now two START awardees and one Wittgenstein and ERC Advanced Grant laureate in our group, almost the highest density of these prizes anywhere!
- Matthias Müllner joins as a PhD student and Michele Riva, who visited with us from the Politecnico Milano previously, returned as post-doc. Matthias will work on our electrochemistry project, and Michele on the oxide PLD. Here the two of them are captured during our daily lunch in the Mensa.
- Today we watched the solar eclipse. Here you can see Michael, the most professional hobby astronomer ever, catching it on camera.
- 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.

- 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.
- Bernhard Stöger successfully defends his PhD thesis entitled “Surface Defects and Adsorption on Strontium Ruthenates”. He was supported by the SFB 'Functional Oxide Surfaces and Interfaces (FOXSI)'. He is moved on to do good things at ZKW group in Wieselburg.
- Michele Riva, who has spent the last seven months in our laser-MBE lab, is going back home to Politecnico di Milano to finish his Ph.D. thesis.

As a farewell, she gives a presentation of her research to her advisor, Prof. Petra de Jongh, with the group listening in. Jessi shows us beautiful results on Pt nanoclusters and their role in catalysis. Watch out for papers to come!
- Bernhard wins the jackpot of the group's soccer world cup bet, and is obliged to treat us all to beer. Also, his paper “A strong chemical reaction of CO with the surface of Sr3Ru2O2” by B. Stöger et al. has been accepted in PRL. Time for a a little Happy Hour.
- Several papers got accepted this week: “A direct view of polarons in TiO2 rutile and anatase” by Martin Setvin et al. in PRL; “Reducing the In2O3(111) Surface Results in Ordered Indium Adatoms” by Margareta Wagner et al. in Advanced Materials Interfaces; “Stabilizing Single Ni adatoms on a Two-dimensional Porous Titania on SrTiO3(110) Surface” by Zhiming Wang et al. in J.

- Our paper “Surface preparation of TiO2 anatase (101): Pitfalls and how to avoid them” by Martin Setvin et al. made it on the front page of the newest issue of 'Surface Science'.
- The Austrian Academy of Sciences ÖAW has different levels of membership. Ulrike Diebold has been a 'corresponding member' since 2012, and was elected a 'full member' in April 2014.
- The surface physics group gets additional help. Our new “UHV Technician”, Martin Leichtfried, joins us.
- 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.
- Three students started in our group this month. The photo shows (from left to right) Jakub Piastek from Brno, Czech Republic; Jessi van der Hoeven from Utrecht, Netherlands; and Michele Riva from Milan, Italy. Our new friends will be staying with us for 6 months and will participate in various research projects. Jessi and Jakub are supported by the Erasmus program.
- Our group helped organize the 27th '3S conference in St. Christoph/Arlberg. With more than 80 participants, excellent science, and enjoyable outdoor activities the conference was a success.
- 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.
- We have been challenged to play soccer ('football' for the Brits amongst us) by the Solid State Theory group. So we have been practicing. The first time, the old people won against the young'uns. The second time the Österreicher against the Ausländer.
- This year's Lise Meitner Lecture is given by Prof. Jocelyn Bell Burnell (Oxford University) on Tuesday, November 12, 2013, 17h at the Prechtl Saal of the TU. Prof. Bell Burnell will be talking about her breakthrough discovery - pulsars. The Lise Meitner Lectures are public talks held by famous female physicist in memory of the great Lise Meitner. The event is sponsored by the Austrian Physical Society and organized by our institute.
- This month we are welcoming two esteemed visitors. Prof. Patricio Haberle from Universidad Técnica Federico Santa María in Valparaiso, Chile, will work with us for one month. Prof. Jiang-Li Cao from the the University of Science and Technology Beijing will be participating in our research project on perovskite thin films and surfaces.
- Vera Mansfeldova, from the J. Heyrovsky Institute of Physical Chemistry visits us for three months. Her stay is sponsored by the COST Action Reducible oxide chemistry, structure and functions.
- Zbynek Novotny successfully defends his dissertation entitled 'The Reconstructed Fe3O4(001) Surface as an Adsorption Template'. Prof. Igor Shvets from Trinity College, Dublin, serves as the second examiner. After the successful defense, Zbynek throws a great party with lots of Czech beer. Well, done, Z!
- 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.
- Jan Balajka joins our group as a PhD student. Together with Stijn Mertens, he will work on electrochemical studies of oxides.
- Last week, Gareth was selected as the winner of the US Department of Energy Postdoctoral Researcher Competition at the EFRC PI meeting in Washington DC. There he gave a talk entitled “Adsorbate Induced Adatom Mobility in a Model Catalyst: Pd/Fe3O4.”
- Today, our group was honored by a visit of the Austrian Federal Minister for Science and Research, Prof. Dr. Karlheinz Töchterle. He visited our labs and discussed ongoing and planned research with group members.
- Margareta Wagner joins the group as a post-doc. She graduated from the University of Graz, where she worked with Falko Netzer and Mike Ramsey.
- 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.

- 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.
- Ulrike Diebold has received a prestigious ERC Advanced Grant for her project OxideSurfaces, which will be funded with up to 2.5M Euro, and will run over 5 years. The project focuses on metal oxides. These materials have an extremely wide range of physical and chemical properties, and are used in catalysis, solar cells, batteries, gas sensors, and many other technical areas. Research topics are the interaction between bulk and surface defects, complex oxides, and she will also aim at scanning probe microscopy of oxides with atomic resolution in an aqueous solution.
- Ulrike Diebold received an invitation to join the editorial board of Physical Review Letters (PRL). She will act as an associate editor for the Material Physics Division from 2012 - 2014.
