Second-Harmonic Imaging of Magnetic Domains in Thin Film Hematite
Holger Mirkes, Johannes Schmuck, Katharina Müller +7
Hematite is an antiferromagnetic oxide and candidate altermagnetic insulator whose Néel order reorients from an easy-axis to an easy-plane phase at the Morin transition. Interpret…
Ultrafast photo-thermoelectric currents in graphene junctions in the mid-infrared
Nina Pettinger, Michel Panhans, Johannes Schmuck +8
Graphene is widely recognized for its ultrafast and broadband photocurrent response, but whether the broadband ultrafast characteristics are preserved at mid-infrared wavelengths w…
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…
Creation and Microscopic Origins of Single-Photon Emitters in Transition Metal Dichalcogenides and Hexagonal Boron Nitride
Amedeo Carbone, Diane-Pernille Bendixen-Fernex de Mongex, Arkady V. Krasheninnikov +6
We highlight recent advances in the controlled creation of single-photon emitters in van der Waals materials and in the understanding of their atomistic origin. We focus on quantum…
In-situ profiling of pressure-induced exciton traps in suspended MoS monolayers
Leonard Geilen, Lukas Schleicher, Alexander Musta +4
We demonstrate the in-situ read-out of the spatial profile of suspended MoS monolayers hosted on substrates with nano-structured holes. As the profiles are spatially bent, the…
Quantifying the creation of negatively charged boron vacancies in He-ion irradiated hexagonal boron nitride
Amedeo Carbone, Ilia D. Breev, Johannes Figueiredo +10
Hexagonal boron nitride (hBN) hosts luminescent defects possessing spin qualities compatible with quantum sensing protocols at room temperature. Vacancies, in particular, are readi…
