Maßgeschneiderte Materialien: Doktoratskolleg verlängert

Im Doktoratskolleg „Solids4Fun“ werden Materialeigenschaften erforscht, erklärt und verbessert. Der FWF verlängert das erfolgreiche Programm nun um vier Jahre.

Die Eigenschaften eines Materials werden nicht nur durch seine chemische Zusammensetzung festgelegt. Auch viele andere Parameter wie etwa seine Kristallstruktur oder seine Oberflächeneigenschaften können das Materialverhalten entscheidend beeinflussen. Seit vier J ahren läuft an der TU Wien das interdisziplinäre Doktoratskolleg „Solids4Fun. Arbeitsgruppen aus den Bereichen Chemie, Physik und Elektrotechnik haben sich in diesem Kolleg zusammengeschlossen und mit großem Erfolg gemeinsam geforscht. Nach einer erfolgreichen Beguta chtung durch den österreichischen Wissenschaftsfonds FWF wurde „Solids4Fun“ nun um vier Jahre verlängert. Damit erhalten 35 weitere Doktoratsstudierende die Chance auf eine erstklassige Forschungsausbildung.

Vielfältiges Forschungsprogramm

„Materials and Matter“ ist einer der fünf Forschungsschwerpunkte der TU Wien, genau für diesen Bereich leistet das Doktoratskolleg einen wichtigen Beitrag. „Wir vereinen Fachgebiete mit ganz unterschiedlichen Denkweisen und Fachsprachen, und das ist in der moderne n Materialwissenschaft sehr wichtig“, sagt Prof. Andrei Pimenov vom Institut für Festkörperphysik. Er ist nun in der Verlängerungsperiode Sprecher des Doktoratskollegs, in dieser Funktion löst er Prof. Ulrich Schubert (Institut für Materialchemie) ab, der das Kolleg bisher nach außen vertreten hat. „Bei uns bekommen die Studierenden einen breiten, interdisziplinären Überblick über den aktuellen Forschungsstand der Materialwissenschaft – das fehlt bei anderen, spezialisierteren Programmen oft“, sagt Pimenov.

We welcome Hamad Bukhari

Hamad received an IRSIP (International Research Support Initiative) scholarship and will support our group till 08/30/2015.



We welcome Dr. Enda Scally

Enda joined the group in the end of 2014. He holds a PhD in physics from the University College Dublin. His work was based on spectroscopic studies of laser produced plasmas (LPP) in the soft X-Ray and Extreme Ultraviolet (EUV) region using various atomic structure a nd plasma dynamic codes. Experiments for improving broad-band and narrow-band emission in the soft X-Ray, EUV region using alloy and layer target geometries employing nano and pico-second laser systems. Work on renewable liquid collector optics in the EUV region and development of a nano-second grazing incidence spectrometer.

FWF – postdoctoral and doctoral positions



There is an opening for a doctoral position in our research group with a new FWF project.
The aim of the project is the investigation and determination of the origin of giant magnetoelectric effects in new magnetic and multiferroic materials, using broadband dielectric (optical) spectroscopy. Applications within other research topics of the group are possible as well.

Highly qualified and motived national and international students are invited to apply.
Depending upon the qualifications, either doctoral or postdoctoral position is possible.

Vienna is a fine location as regards culture and nature.

Please send an application to Andrei Pimenov

Breakthrough Light Transistor

Our group introduces a new methode to rotate the polarization direction of light simply by applying an electrical voltage to a specific material. This allows to build a transistor that works not with electricity but with light. (read more) (and read more) (Article)

We welcome Dr. Elizabeth John

Elizabeth joined the group in April 2013. She did her masters in Physics from Mahatma Gandhi University, Kerala, India followed by masters in Education from University of Madras, Tamilnadu, India. Later did her doctoral studies in Physics at Charles University, Prague, Czech Republic. Her doctoral work was on the spectroscopic investigation of lattice dynamics in multidomain ferroelectrics using Infrared and Raman spectroscopy and PFM (Piezoresponse Force Microscopy) imaging.

We welcome Dr. Graeme Johnstone

Graeme joined the group in the beginning of 2013. He began his studies in physics at the University of St Andrews, then moved to the University of Oxford to study for his doctorate. At Oxford, his research was focused using both neutron and resonant x-ray scattering to investigate magnetism in manganite materials such as colossal magnetoresistance manganites and multiferroics.

Wlad Dziom joins the group

We welcome Wlad Dziom into the group. Wlad studied physics at the famous Institute of Physics and Technology and did his master work at the Institute of Solid State Physics in Chernogolovka. His previous work is devoted to sensitive microwave experiments of supercond uctors in external magnetic field. He will support our activities in terahertz spectroscopy.
