The SPECSY group investigates solid-liquid interfaces by a combination of electronic structure modelling and experimental optical spectroscopy. The aim is to understand on an atomistic level the structure of electrochemical interfaces as a function of the potential applied to the electrode. We address the challenge to convey this information through the liquid electrolyte in a time-resolved manner by employing the highly interface-sensitive optical technique reflection anisotropy spectroscopy in electrochemical environments. The experimental spectra are then interpreted with the aid of computational spectroscopy on top of an electronic structre from density functional theory. Our approach will help to understand ion adsorption and corrosion processes in solar fuel devices and batteries.

  • 23/10/2021 On Thursday, Matthias was awarded the Curious Minds Award 2021 by Merck and Manager Magazin in the section 'Energy and Mobility'. Thanks to the jury and the sponsors! Michael Saliba, on of our partners in the NETPEC project, won the prize in the category 'Materials and Active Substances', congratulations! On the same day, the founders of Biontech, Özlem Türeci and Uğur Şahin, were honored for their great and inspiring work on mRNA vaccines and introduced into the Hall of Fame der deutschen Forschung. Congrats and thanks for their work!
  • 20/09/2021 We have two more open positions, also at Universität Tübingen in the exciting NETPEC-project on negative emissions by photoelectrochemical approaches. One position is an experimental postdoc position on operando RAS at catalyst-electrolyte interfaces. The other position is a computational PhD position for modelling and atomistically understanding what we see on these interfaces by means of denisty functional theory and computational spectroscopy.
