Our group aims to understand the fundamental interactions and processes at atomic length and time scales that determine the limits of material performance for energy-relevant applications, such as (photo)catalysis, photovoltaics, batteries, or data storage. We develop and use advanced spectroscopic and microscopic tools based on X-ray and electron probes. In particular, at large-scale X-ray facilities we employ photoelectron spectroscopy to unravel interactions at solid-electrolyte interfaces, and time-resolved X-ray spectroscopy to elucidate fast light-induced energy- and charge-transfer processes in molecular and solid-state systems. As part of the CatLab project, we develop an ultrafast transmission electron microscope capable of taking Read more
