Your tasks

In the framework of this work, we will implement a new experimental technique, combining low temperature scanning tunneling and ultrafast near-field spectroscopy, to probe optical fields in functional nanostructures with sub-femtosecond time and nanometer spatial resolution (see e.g., T. Jehle et al. Nano Lett. 26, 2604 (2026)). The planned experiments shall give conceptually new insight into energy- and charge transfer phenomena in nanoscale quantum materials. The research is embedded in the Center for Nanoscale Dynamics ( https://uol.de/en/physics/dynano-dynamics-at-the-nanoscale-1 ) and funded by the Deutsche Forschungsgemeinschaft and the Niedersächsisches Ministerium für Wissenschaft und Kultur (DyNano). The research will be performed in close collaboration with the Scanning Probe Spectroscopy group (N. Nilius) in Oldenburg using a new custom-designed low-temperature ultrafast STM/AFM system. The postdoctoral researcher is expected to take the lead of this new project.
