A diary of some remarkable events in the Surface Physics group…


Peter Varga 1946-2018

Peter_Varga 2018-Oct-27

* With great sadness we announce that our colleague Peter Varga has passed on October 27, 2018. Peter Varga was the founder and longtime head of the Surface Physics Group at the Institute of Applied Physics (IAP), and he shaped it into one of world's leading centers of surface physics. Having retired as Professor at the TU Wien in 2011, he nevertheless remained an active member of our group and also kept contact with our friends in Brno where he had a “PostProf” position at CEITEC. His funeral took place on Monday, November 5, 2018 in Maria Enzersdorf (Romantikerfriedhof, Grenzgasse 7). The Institute of Applied Physics mourns the loss of a long-time colleague and a good friend!

  • Jan Balajka successfully defends his PhD thesis entitled “Interaction of Titanium Dioxide Surfaces with Liquid Water” with Prof. Miquel Salmeron from Berkeley acting as a most knowledgeable opponent. Jan passes with distinction, and they both pose for a picture at the UHV system 'Omega' that was Jan's sorrow and joy for the past few years. Congratulations!


The Joys of Attending Conferences

2018-August Happy at AirBnB

  • Our group has a strong showing at this year's ECOSS conference in Aarhus, Denmark. We present many talks, learn a lot of new science, make new friends, and enjoy each other's company.


The Importance of Trace Impurities and how to Avoid them

2018-Aug-24 The cleanest water drop comes from an icicle

  • Titanium dioxide (TiO2) is highly versatile material, used, e.g., for self-cleaning mirrors. When bringing one of its surfaces in contact with water, researchers around the world have observed a structure that was interpreted as ordering of water molecules or caused by carbon dioxide dissolved in the water. Jan Balajka and colleagues of the IAP surface physics group, together with Melissa Hines (Cornell University) could disprove these ideas. They have used what is probably the purest water drop on Earth, created from an icicle in ultrahigh vacuum (see photo). Surprisingly, the TiO2 surface structures turned out to come from trace impurities in the atmosphere such as formic acid, present in concentrations of only 1:1000000000! These results were published in the prestigeous journal Science.

Bakeout

2018-May-09 Zhiyu with his signature sign

  • In order to achieve excellent ultrahigh vacuum, a bakeout of the vacuum chamber is required that can last up several days. Sometimes this makes the security personnel in our building nervous. To prevent them from raising alarm, and calling us – typically in the middle of the night on weekends – Zhiyu designs this most helpful sign.


Spring Kebap: Record Turnout

2018-April-12 Lunch in the park

  • Spring is finally here. Following our annual tradition, we take advantage of one of the first warm days to storm our favorite kebap stand at Naschmarkt. Everyone comes along to hang out at the park and eat.


Vibration Isolation Patent

2018-March-20 High-resolution microscope suspended for vibration isolation

  • The Surface Physics Group has patented a device for suspending a load in a vibration-insulated manner, designed for high-resolution microscopy and nanotechnology. While other similar instruments are usually placed in the basement of a building in a quiet environment, the low-temperature non-contact AFM/STM at the IAP/TU Wien suspended according to the invention delivers excellent performance in spite of its place in the 5th floor of a building in downtown Vienna! The patented vibration isolation system also features accurate levelling even under changing load distribution during operation.

For more information, see the TU press release (English, German), the Youtube movie, article in Der Standard or the Feature in Nature on high-performance microscopy

Avoiding the Polar Catastrophe

The labyrinth is the way out 2018-Feb-02

* Ionic crystals - materials that are composed of positively and negatively charged ions - can be put into a highly unfavorable situation. When split in half along certain crystallographic directions the electrostatic energy diverges. To alleviate this so-called polar catastrophe, materials can react in a variety of ways. In a recent paper, Martin Setvin and co-workers from the Surface Physics group and from the University of Vienna show the surface of a KTaO3(001) single crystal after cleaving, heating, and exposure to water vapor. Six different mechanisms to compensate polarity are encountered. One of the most pretty solutions, a nano-labyrinth with 4-5 atom-wide walls, is shown in the image on the right.

Featuring Polarons: PRX and Nature Reviews

2017-October-15 Nc-AFM of 1x2

  • For a long time the (1×2) reconstruction of one of our favorite materials - rutile TiO2(110) - has puzzled us, and many of our colleagues world-wide. Based on Martin Setvin's beautiful STM/AFM results, our DFT friends at the University of Vienna have figured out that polarons are of essence. Our paper, which appeared in PRX earlier this month, has caught the eye of one of the editors of Nature Reviews.


How to Sputter-Deposit Ultrathin Films

2017-October-06 Sputter source glowing

  • In surface science it is essential to cleanly grow ultrathin films with a carefully-controlled thickness of less than one monolayer. For some materials (zirconium, say), this is difficult: Even though the melting point is exceedingly high, the vapor pressure is low. To circumvent this problem we have refined a UHV-compatible sputter deposition source. Read here how our source works and how well it performs.


Tenure for Gareth Parkinson

2017-September-01 Gareth and his research group

  • We are extremely pleased to learn that Gareth Parkinson has been promoted to Associate Professor with tenure. He will continue his highly-successful research into the surface science of heterogeneous catalysis together with his growing surface physics subgroup focused on iron oxides.

Traditional Spring Kebap

 Kebap at Naschmarkt  Erasmus students trying new maneuvers

2017-March-28

  • Earlier than usual, spring has arrived this year. Temperatures will reach 25°C here in Vienna on the weekend, so we hurry to eat our traditional spring kebap before summer arrives. Our Erasmus students from Brno university meanwhile relax while driving their new car.


Switching Oxygen Molecules On and Off

2017-March-14 The qPlus sensor with the tip at the left

  • The oxygen molecule O2 is chemically inert (except at high temperatures), but becomes reactive when an additional electron gets added. This process happens in biology, catalysis and can be also triggered by light on some surfaces. Martin Setvin of the Surface Physics Group managed to switch oxygen molecules adsorbed at a titanium dioxide surface back and forth between the non-reactive (neutral) and reactive (O2-) state and examine them in detail using non-contact atomic-force microscopy (nc-AFM) with the tiny tip of a so-called qPlus sensor (image). The results were published in the prestigious journal Proceedings of the National Academy of Sciences of the USA (PNAS).

We wish the beautiful couple much happiness and continued success.

The Pairing and Separation of Pt Atoms

2016-July-28 A Pt dimer at the Fe<sub>3</sub>O<sub>4</sub> surface

  • Sintering - the aggregation of catalytically active, metallic nanoparticles into bigger clumps - is one of the major causes of catalyst de-activation. This is particularly important in the emerging field of single-atom catalysis, the main research topic of the START project of Gareth Parkinson. A detailed STM and DFT study, mainly conducted by Roland Bliem, and published in PNAS, shows how single Pt atoms on the Fe3O4(001) surface are made mobile by CO, and how they merge into bigger clusters. Interestingly, the smallest cluster, a Pt dimer, is stabilized by the CO molecules. When the sample is heated, and the CO desorbs, and the two Pt atoms separate again.

Making it Stick on the Cover of Nature

2016-June-30

  • The article "Switching stiction and adhesion of a liquid on a solid" by Stijn Mertens et al. is featured on this week's cover of Nature Magazine. The work describes dynamic contact angle measurements of a single drop of 0.1 M HClO4 on a single layer of BN supported on Rh(111). Friction can be changed reversibly by applying an appropriate electrochemical potential that leads to the intercalation of H between BN and the Rh.


The Group Bikes
