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…
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…
Mapping the Optical Landscape of a Squaraine Molecule in the Visible and Ultraviolet Energy Range
Narges Taghizade, Robert Schwarzl, Frederik Leinenbach +9
Although squaraine dyes are commonly praised as candidates for light-based applications, little is known about their excited state landscape beyond the low-energy visible light reg…
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…
