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…

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…
