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…
Time-domain observation of interlayer exciton formation and thermalization in a MoSe/WSe heterostructure
Veronica R. Policht, Henry Mittenzwey, Oleg Dogadov +11
Vertical heterostructures (HS) of transition metal dichalcogenides (TMDs) host interlayer excitons (ILX), with electrons and holes residing in different layers. With respect to the…
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…
Suppression and amplification of phonon sidebands in transition metal dichalcogenides by optical feedback
Thomas Tenzler, Andreas Knorr, Manuel Katzer
Transition metal dichalcogenides (TMDCs) combine both strong light-matter-interaction and strong Coulomb-interaction for the formation of optically excitable excitons. Through radi…
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.…
