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…
Ultra-Sensitive Extinction Measurements of Optically Active Defects in Monolayer MoS
Florian Sigger, Ines Amersdorffer, Alexander Hötger +12
We utilize cavity-enhanced extinction spectroscopy to directly quantify the optical absorption of defects in MoS generated by helium ion bombardment. We achieve hyperspectral i…
Optical dipole orientation of interlayer excitons in MoSe-WSe heterostacks
Lukas Sigl, Mirco Troue, Manuel Katzer +10
We report on the far-field photoluminescence intensity distribution of interlayer excitons in MoSe-WSe heterostacks as measured by back focal plane imaging in the tempe…
Charged exciton kinetics in monolayer MoSe near ferroelectric domain walls in periodically poled LiNbO
Pedro Soubelet, Julian Klein, Jakob Wierzbowski +5
Monolayers of semiconducting transition metal dichalcogenides are a strongly emergent platform for exploring quantum phenomena in condensed matter, building novel opto-electronic d…
Control of the orbital character of indirect excitons in MoS2/WS2 heterobilayers
Jonas Kiemle, Florian Sigger, Michael Lorke +5
Valley selective hybridization and residual coupling of electronic states in commensurate van der Waals heterobilayers enable the control of the orbital character of interlayer exc…
Atomistic defect states as quantum emitters in monolayer MoS
Julian Klein, Michael Lorke, Matthias Florian +12
Quantum light sources in solid-state systems are of major interest as a basic ingredient for integrated quantum device technologies. The ability to tailor quantum emission through…
Hybridized indirect excitons in MoS2/WS2 heterobilayers
Jonas Kiemle, Florian Sigger, Michael Lorke +5
Ensembles of indirect or interlayer excitons (IXs) are intriguing systems to explore classical and quantum phases of interacting bosonic ensembles. IXs are composite bosons that fe…
Robust valley polarization of helium ion modified atomically thin MoS
Julian Klein, Agnieszka Kuc, Anna Nolinder +8
Atomically thin semiconductors have dimensions that are commensurate with critical feature sizes of future optoelectronic devices defined using electron/ion beam lithography. Robus…
Direct exciton emission from atomically thin transition metal dichalcogenide heterostructures near the lifetime limit
Jakob Wierzbowski, Julian Klein, Florian Sigger +9
We demonstrate the reduction of the inhomogeneous linewidth of the free excitons in atomically thin transition metal dichalcogenides (TMDCs) MoSe, WSe and MoS by…
