Tracing the film structure of an organic semiconductor with photoemission orbital tomography
Monja Stettner, Siegfried Kaidisch, Andrey V. Matetskiy +7
Photoemission orbital tomography (POT) is a powerful tool for investigating the orbitals and electronic band structure of oriented layers of organic molecules. In many cases, POT a…

Photoemission tomography of excitons in 2D systems: momentum-space signatures of correlated electron-hole wave functions
Siegfried Kaidisch, Amir Kleiner, Sivan Refaely-Abramson +2
The momentum-space signatures of excitons can be experimentally accessed through time-resolved (pump-probe) photoelectron spectroscopy. In this work, we develop a computational fra…

Observing the spatial and temporal evolution of exciton wave functions
Marcel Theilen, Siegfried Kaidisch, Monja Stettner +12
Excitons, the correlated electron-hole pairs governing optical and transport properties in organic semiconductors, have long resisted direct experimental access to their full quant…
