Coulomb Interaction and Density-Independent Exciton-Scattering Processes in Atomically Thin Semiconductors
Henry Mittenzwey, Andreas Knorr, Thorsten Deilmann
In quantum-kinetic approaches to the dynamics of Coulomb-bound many-body correlations such as excitons, trions, biexcitons or higher-order correlations, a detailed knowledge of the…
Excitonic Theory of the Ultrafast Optical Response of 2D-Quantum-Confined Semiconductors at Elevated Densities
Henry Mittenzwey, Oliver Voigt, Andreas Knorr
An excitonic approach to the ultrafast optical response of confined semiconductors at elevated densities below the Mott transition is presented. The theory is valid from the cohere…
Theory of In-Plane-Magnetic-Field-Dependent Excitonic Spectra in Atomically Thin Semiconductors
Michiel Snoeken, Paul Steeger, Robert Schmidt +4
The linear absorption spectrum of excitons in TMDC monolayers under the influence of an in-plane magnetic field is theoretically studied. We demonstrate that in-plane magnetic fiel…
Many-Body Rashba Spin-Orbit Interaction and Exciton Spin Relaxation in Atomically Thin Semiconductor Structures
Henry Mittenzwey, Andreas Knorr
We propose a pair spin-orbit interaction (PSOI) mechanism by establishing a mesoscopic many-particle Rashba Hamiltonian. In lowest order, this Hamiltonian self-consistently describ…
Dissecting intervalley coupling mechanisms in monolayer transition metal dichalcogenides
Oleg Dogadov, Henry Mittenzwey, Micol Bertolotti +8
Monolayer (1L) transition metal dichalcogenides (TMDs) provide a unique opportunity to control the valley degree of freedom of optically excited charge carriers due to the spin-val…
Ultrafast Optical Control of Rashba Interactions in a TMDC Heterostructure
Henry Mittenzwey, Abhijeet Kumar, Raghav Dhingra +6
We investigate spin relaxation dynamics of interlayer excitons in a MoSe2/MoS2 heterostructure induced by the Rashba effect. In such a system, Rashba interactions arise from an out…
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…
Unconventional double-bended saturation of optical transmission in graphene due to many-particle interactions
Torben Winzer, Martin Mittendorff, Stephan Winnerl +3
We present a joint theory-experiment study on the transmission/absorption saturation after ultrafast pulse excitation in graphene. We reveal an unconventional double-bended saturat…
