Zero-phonon line emission of single photon emitters in helium-ion treated MoS
Katja Barthelmi, Tomer Amit, Mirco Troue +13
We explore the zero-phonon line of single photon emitters in helium-ion treated monolayer MoS, which are currently understood in terms of single sulfur-site vacancies. By compa…
Spectrally resolved far-field emission pattern of single photon emitters in MoS2
Katja Barthelmi, Tomer Amit, Lukas Sigl +9
We explore the optical dipole orientation of single photon emitters in monolayer MoS2 as produced by a focused helium ion beam. The single photon emitters can be understood as sing…
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…
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…
Scalable single-photon sources in atomically thin MoS2
Julian Klein, Lukas Sigl, Samuel Gyger +13
Real-world quantum applications, eg. on-chip quantum networks and quantum cryptography, necessitate large scale integrated single-photon sources with nanoscale footprint for modern…
Condensation signatures of photogenerated interlayer excitons in a van der Waals heterostack
Lukas Sigl, Florian Sigger, Fabian Kronowetter +7
Atomistic van der Waals heterostacks are ideal systems for high-temperature exciton condensation because of large exciton binding energies and long lifetimes. Charge transport and…
