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…
Exciton g-factors in monolayer and bilayer WSe from experiment and theory
J. Förste, N. V. Tepliakov, S. Yu. Kruchinin +7
The optical properties of monolayer and bilayer transition metal dichalcogenide semiconductors are governed by excitons in different spin and valley configurations, providing versa…
Signatures of defect-localized charged excitons in the photoluminescence of monolayer molybdenum disulfide
Andre Neumann, Jessica Lindlau, Manuel Nutz +3
We study spatial photoluminescence characteristics of neutral and charged excitons across extended monolayer MoS synthesized by chemical vapor deposition. Using two-dimensional…
Opto-valleytronic imaging of atomically thin semiconductors
Andre Neumann, Jessica Lindlau, Léo Colombier +6
Transition metal dichalcogenide semiconductors represent elementary components of layered heterostructures for emergent technologies beyond conventional opto-electronics. In their…
Tuning the Fröhlich exciton-phonon scattering in monolayer MoS2
Bastian Miller, Jessica Lindlau, Max Bommert +5
A direct band gap, remarkable light-matter coupling as well as strong spin-orbit and Coulomb interaction establish two-dimensional (2D) crystals of transition metal dichalcogenides…
Cavity-control of bright and dark interlayer excitons in van der Waals heterostructures
Michael Förg, Léo Colombier, Robin K. Patel +5
Monolayer (ML) transition metal dichalcogenides (TMDs) integrated in optical microcavities host exciton-polaritons as a hallmark of the strong light-matter coupling regime. Analogo…
The role of momentum-dark excitons in the elementary optical response of bilayer WSe
Jessica Lindlau, Malte Selig, Andre Neumann +6
Monolayer (ML) transition metal dichalcogenides (TMDs) undergo substantial changes in the single-particle band structure and excitonic optical response upon the addition of just on…
Identifying optical signatures of momentum-dark excitons in transition metal dichalcogenide monolayers
Jessica Lindlau, Cedric Robert, Victor Funk +12
Transition metal dichalcogenide (TMD) monolayers (MLs) exhibit rich photoluminescence spectra associated with interband optical transitions of direct-gap semiconductors. Upon absor…
Contamination of polymethylmethacrylate by organic quantum emitters
Andre Neumann, Jessica Lindlau, Alexander Högele
We report the observation of ubiquitous contamination of polymethylmethacrylate by organic molecules with optical activity in the visible spectral range. Contamination sites of ind…
