Fermionic vs. bosonic thermalization in the phonon-driven exciton dynamics: An analytic dimensionality study
Manuel Katzer, Malte Selig, Andreas Knorr
Excitons are compound particles formed from an electron and a hole in semiconductors. The impact of this substructure on the phonon-exciton interaction is described by a closed sys…
Exciton-phonon-scattering: A competition between bosonic and fermionic nature of bound electron-hole pairs
Manuel Katzer, Malte Selig, Lukas Sigl +7
The question of macroscopic occupation and spontaneous emergence of coherence for exciton ensembles has gained renewed attention due to the rise of van der Waals heterostructures m…
Extended spatial coherence of interlayer excitons in MoSe/WSe heterobilayers
Mirco Troue, Johannes Figueiredo, Lukas Sigl +8
We report on the spatial coherence of interlayer exciton ensembles as formed in MoSe/WSe heterostructures and characterized by point-inversion Michelson-Morley interferomet…
Impact of dark excitons on Förster type resonant energy transfer between dye molecules and atomically thin semiconductors
Manuel Katzer, Sviatoslav Kovalchuk, Kyrylo Greben +3
Interfaces of dye molecules and two-dimensional transition metal dichalcogenides (TMDCs) combine strong molecular dipole excitations with high carrier mobilities in semiconductors.…
Negative-mass exciton polaritons induced by dissipative light-matter coupling in an atomically thin semiconductor
M. Wurdack, T. Yun, M. Katzer +5
Dispersion engineering is a powerful and versatile tool that can vary the speed of light signals and induce negative-mass effects in the dynamics of particles and quasiparticles. H…
Impact of optically pumped non-equilibrium steady states on luminescence emission of atomically-thin semiconductor excitons
Malte Selig, Dominik Christiansen, Manuel Katzer +3
The interplay of the non-equivalent corners in the Brillouin zone of transition metal dichalcogenides have been investigated extensively. While experimental and theoretical works c…
