Growth-controlled suppression of electrically active defects in CrSBr
Sara R. Tulchinsky, Sergii Grytsiuk, Shen van Hassel +7
In CrSBr, as in many crystalline materials, the type and density of defects are expected to strongly influence material behavior. Identifying the underlying atomic defect configura…
Dielectric environment sensitivity of carbon centres in hexagonal boron nitride
Danis I. Badrtdinov, Carlos Rodriguez-Fernandez, Magdalena Grzeszczyk +11
A key advantage of utilizing van der Waals materials as defect-hosting platforms for quantum applications is the controllable proximity of the defect to the surface or the substrat…
Dielectric tunability of magnetic properties in orthorhombic ferromagnetic monolayer CrSBr
Alexander N. Rudenko, Malte Rösner, Mikhail I. Katsnelson
Monolayer CrSBr is a recently discovered semiconducting spin-3/2 ferromagnet with a Curie temperature around 146 K. Unlike many other known two-dimensional (2D) magnets, CrSBr has…
Common microscopic origin of the phase transitions in TaNiS and the excitonic insulator candidate TaNiSe
Lukas Windgätter, Malte Rösner, Giacomo Mazza +5
The structural phase transition in TaNiSe has been envisioned as driven by the formation of an excitonic insulating phase. However, the role of structural and electronic in…
Quantum embedding methods for correlated excited states of point defects: Case studies and challenges
Lukas Muechler, Danis I. Badrtdinov, Alexander Hampel +3
A quantitative description of the excited electronic states of point defects and impurities is crucial for understanding materials properties, and possible applications of defects…
Nonequilibrium Carrier Dynamics in Transition Metal Dichalcogenide Semiconductors
Alexander Steinhoff, Matthias Florian, Malte Rösner +4
When exploring new materials for their potential in (opto)electronic device applications, it is important to understand the role of various carrier interaction and scattering proce…
Wannier Function Approach to Realistic Coulomb Interactions in Layered Materials and Heterostructures
M. Rösner, E. Şaşıoğlu, C. Friedrich +2
We introduce an approach to derive realistic Coulomb interaction terms in free standing layered materials and vertical heterostructures from ab-initio modelling of the correspondin…
Separation of ultrafast spin currents and spin-flip scattering in Co/Cu(001) driven by femtosecond laser excitation via the complex MOKE
J. Wieczorek, A. Eschenlohr, B. Weidtmann +5
Ultrafast magnetization dynamics in metallic heterostructures consists of a combination of local demagnetization in the ferromagnetic constituent and spin-dependent transport contr…
Phase Diagram of Electron Doped Dichalcogenides
M. Rösner, S. Haas, T. O. Wehling
Using first principle calculations, we examine the sequence of phases in electron doped dichalcogenides, such as recently realized in field-gated MoS. Upon increasing the elect…
