Encapsulated macroscopic WS monolayers enable room-temperature exciton-polariton lattices
Shiyu Huang, Sander Scheel, Jiang Qu +11
Large-area, optically homogeneous monolayer semiconductors are a critical prerequisite for scalable room-temperature polaritonics and for realizing polariton lattices extending acr…
Strain engineering of valley-polarized hybrid excitons in a 2D semiconductor
Abhijeet M. Kumar, Douglas J. Bock, Denis Yagodkin +11
Encoding and manipulating digital information in quantum degrees of freedom is one of the major challenges of today's science and technology. The valley indices of excitons in tran…
Quadrupolar Excitons in MoSe Bilayers
Jakub Jasiński, Joakim Hagel, Samuel Brem +11
The quest for platforms to generate and control exotic excitonic states has greatly benefited from the advent of transition metal dichalcogenide (TMD) monolayers and their heterost…
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…
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…
Spectral asymmetry of phonon sideband luminescence in monolayer and bilayer WSe2
Victor Funk, Koloman Wagner, Edith Wietek +8
We report an experimental study of temperature-dependent spectral lineshapes of phonon side-band emission stemming from dark excitons in monolayer and bilayer WSe. Using phot…
Nonclassical Exciton Diffusion in Monolayer WSe2
Koloman Wagner, Jonas Zipfel, Roberto Rosati +9
We experimentally demonstrate time-resolved exciton propagation in a monolayer semiconductor at cryogenic temperatures. Monitoring phonon-assisted recombination of dark states, we…
Autoionization and dressing of excited excitons by free carriers in monolayer WSe2
Koloman Wagner, Edith Wietek, Jonas D. Ziegler +6
We experimentally demonstrate dressing of the excited exciton states by a continuously tunable Fermi sea of free charge carriers in a monolayer semiconductor. It represents an unus…
Temporal evolution of low-temperature phonon sidebands in WSe monolayers
Roberto Rosati, Samuel Brem, Raül Perea-Causín +9
Low-temperature photoluminescence (PL) of hBN-encapsulated monolayer tungsten diselenide (WSe) shows a multitude of sharp emission peaks below the bright exciton. Some of them…
