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…
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…
