Wannier-Function-Based Approach to Coupled Exciton-Phonon-Photon Dynamics in Two-Dimensional Semiconductors
Alexander Steinhoff, Frank Jahnke, Matthias Florian
Marrying the predictive power of ab initio calculations with many-body effects remains a challenging task in two-dimensional (2d) materials, where efficient carrier-carrier interac…
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…
Microscopic Theory of Exciton-Exciton Annihilation in Two-Dimensional Semiconductors
Alexander Steinhoff, Matthias Florian, Frank Jahnke
Auger-like exciton-exciton annihilation (EEA) is considered the key fundamental limitation to quantum yield in devices based on excitons in two-dimensional (2d) materials. Since it…
Optical nonlinearities in the excited carrier density of atomically thin transition metal dichalcogenides
Daniel Erben, Alexander Steinhoff, Michael Lorke +1
In atomically thin semiconductors based on transition metal dichalcogenides, photoexcitation can be used to generate high densities of electron-hole pairs. Due to optical nonlinear…
Twist Angle Dependent Interlayer Exciton Lifetimes in van der Waals Heterostructures
Junho Choi, Matthias Florian, Alexander Steinhoff +15
In van der Waals (vdW) heterostructures formed by stacking two monolayers of transition metal dichalcogenides, multiple exciton resonances with highly tunable properties are formed…
