to the eDyχ crowd
We warmly welcome Marco Kapitzke and Radoslaw Kaleba in the group! Marco will work on his bachelor thesis using our SNOM while Radek is entirely voluntarily spending his second summer in the group to explore ultrafast science. It is great to have you both!
group meeting in the FHI garden (in front of Fritz Haber’s and Clara Immerwahr’s villa)
(f.l.t.r.: Ste, Angelika, Ines, Lukas, Sam, Boubacar, Zhigang)
|A warm welcome to Ines Mayan and Yin Zhigang!
Ines master project will focus on ultrafast dynamics at oxide-water interfaces, and Zhigang is a visiting researcher on hybrid inorganic/organic systems.
The DFG committee decided that the Collaborative Research Center 951 (Sfb951) will be funded for another four years!
We look forward to inspiring and fruitful work on inorganic-organic hybrid systems within our consortium.
Dr. Mor 🙂
We are proud to announce that Selene successfully defended her PhD thesis
“Fundamental interactions governing the (non-)equilibrium electronic structure in low dimensions“
Oh happy day!!!
Nasty things can be incredibly interesting. This is why Laura & Co. used nearly all time-resolved techniques our lab offers plus high-res spectroscopy of our collaborators at the Humboldt University to finally understand why previous results on ultrafast dynamics in ZnO were conflicting. The competition of intrinsic and defect-related dynamics in ZnO begins on ultrafast timescales, but affects everything that follows…
— Every cloud has a silver lining.
We are happy to announce that Sam Palato has joined the group! He will investigate ultrafast spatio-temporal dynamics in inorganic organic hybrid systems.
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.

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…
…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!

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!
We offer several opportunities for exciting master or bachelor projects in physics & chemisty!
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.
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.
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 🙂
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).
The newest group member is 52 cm tall and weighs 4 kg. Welcome, Hannah!
