Exciton-exciton interactions in van der Waals heterobilayers
Alexander Steinhoff, Edith Wietek, Matthias Florian +7
Exciton-exciton interactions are key to understanding non-linear optical and transport phenomena in van der Waals heterobilayers, which emerged as versatile platforms to study corr…
Engineering the impact of phonon dephasing on the coherence of a WSe single-photon source via cavity quantum electrodynamics
Victor Nikolaevich Mitryakhin, Alexander Steinhoff, Jens-Christian Drawer +13
Emitter dephasing is one of the key issues in the performance of solid-state single photon sources. Among the various sources of dephasing, acoustic phonons play a central role in…
In-situ spontaneous emission control of MoSe-WSe interlayer excitons with near-unity quantum yield
Bo Han, Chirag Chandrakant Palekar, Sven Stephan +12
Optical resonators are a powerful platform to control the spontaneous emission dynamics of excitons in solid-state nanostructures. Here, we study a MoSe-WSe van-der-Waals h…
Non-linear and negative effective diffusivity of optical excitations in moiré-free heterobilayers
Edith Wietek, Matthias Florian, Jonas M. Göser +6
Interlayer exciton diffusion is studied in atomically-reconstructed MoSe2/WSe2 heterobilayers with suppressed disorder. Local atomic registry is confirmed by characteristic optical…
Confined-state physics and signs of fermionization of moiré excitons in WSe/MoSe heterobilayers
Frederik Lohof, Johannes Michl, Alexander Steinhoff +10
We revisit and extend the standard bosonic interpretation of interlayer excitons in the moiré potential of twisted heterostructures of transition-metal dichalcogenides. In our expe…
