Bottom-up realization of a type-II organic-TMD heterointerface: Pentacene on monolayer WS2
Michele Capra, Christian S. Kern, Mira S. Arndt +11
Stacked van der Waals heterostructures based on transition metal dichalcogenides (TMDs) exhibit a rich variety of exotic interfacial phenomena. Substituting one component with an o…
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…
Circular dichroism in the photoelectron angular distribution of achiral molecules
Christian S. Kern, Xiaosheng Yang, Giovanni Zamborlini +9
Circular dichroism in the angular distribution (CDAD) is the effect that the angular intensity distribution of photoemitted electrons depends on the handedness of the incident circ…
Metalloporphyrins on Oxygen-Passivated Iron: Conformation and Order Beyond the First Layer
David Maximilian Janas, Andreas Windischbacher, Mira Sophie Arndt +15
On-surface metal porphyrins can undergo electronic and conformational changes that play a crucial role in determining the chemical reactivity of the molecular layer. Therefore, und…
