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…
Strong Coupling of Two-Dimensional Excitons and Plasmonic Photonic Crystals: Microscopic Theory Reveals Triplet Spectra
Lara Greten, Robert Salzwedel, Tobias Göde +5
Monolayers of transition metal dichalcogenides (TMDC) are direct-gap semiconductors with strong light-matter interactions featuring tightly bound excitons, while plasmonic crystals…
Spatial Exciton Localization at Interfaces of Metal Nanoparticles and Atomically Thin Semiconductors
Robert Salzwedel, Lara Greten, Stefan Schmidt +3
We present a self-consistent Maxwell-Bloch theory to analytically study the interaction between a nanostructure consisting of a metal nanoparticle and a monolayer of transition met…
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…
Theory of radial oscillations in metal nanoparticles driven by optically induced electron density gradients
Robert Salzwedel, Andreas Knorr, Dominik Hoeing +2
We provide a microscopic approach to describe the onset of radial oscillation of a silver nanoparticle. Using the Heisenberg equation of motion framework, we find that the coupled…
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…
