Taming ZnO

Nasty things can be incredibly interesting.

And every cloud has a silver lining.

Multistep and multiscale electron transfer

Sarah, Katharina, and Angelika could show that electron transfer across a model electrode/electrolyte interface is a multistep process, involving complex solvation and localization dynamics.

Soon, we will demonstrate that these dynamics, ranging from femtoseconds to seconds, lie at the origin of an electrochemical reaction chain…

We escaped…

…from the escape room an had an awesome pre-Christmas-pre-welcome-Sam evening including delicious and sudatory Chinese food!
Thanks Angelika & Sele for organizing!

Together with our colleagues at the Humboldt University,
Sesha, Jan, and Lukas uncovered the (un-)occupied electronic structure of a buried hybrid interface!

This work was only possible due to joint “hybridized” forces of the collaborative research center (CRC) 951, combining organic synthesis, PL, PLE, XRD, and 2PPE to access electronic states at an internal interface.

new machine

Just ordered a scattering SNOM at neaspec! – Femtosecond time resolution meets nanometer spatial resolution soon 🙂


Sesha Vempati and Sarah King accepted calls for assistant professorships at the Indian Institute of Technology Bhilai and the University of Chicago, respectively.
We wish you all the best for the future, Prof. Vempati and Prof. King!

bachelor/master projects

We offer several opportunities for exciting master or bachelor projects in physics & chemisty!

More information can be found here: in English and auf Deutsch 🙂

meet you at DIET16

The abstract submission and registration of this year’s DIET meeting at the Eibsee at the foot of the Zugspitze is now open.

recalcitrant material

Ta2NiSe5 does not want to undergo photoinduced phase transitions. Selene Mor‘s experiments show that it self-protects from a structural phase transition and, instead of undergoing an insulator-to-semiconductor phase transition, becomes more insulating through exciton condensate density enhancement when photoexcited sufficiently strongly.

excellent posters

by Sarah King and Lukas Gierster have been awarded! Congratulations!

new laser system arrived

Our new laser system (Light Conversion PHAROS/ORPHEUS-2N/3N) is a true swiss army knife for pump-probe experiments. Customized for our needs, it provides ultrashort (30-40 fs) laser pulses with tunable repetition rate and wavelength (1300-270 nm). Moreover, it is software-controlled! -Now we can do ultrafast ultrafast experiments 🙂

water splitting

Sarah King and Daniel Wegkamp showed that amorphous solid water layers adsorbed on Cu(111) host extremely long-lived excess electrons that can drive the two-electron hydrogen evolution reaction.

on the move…

The electron dynamiX team and lab moved to the new building! Come and visit us in house G on the FHI campus (map).

new arrival!

The newest group member is 52 cm tall and weighs 4 kg. Welcome, Hannah!
