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…
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…
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…
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…
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…
