Twin Domains in Van der Waals Quaternary Oxides
Dorothée S. Mader, Niels Brumby, Xiaosheng Yang +10
Optical anisotropy is the basis for many intriguing phenomena in van der Waals materials, including hyperbolic polaritons and extreme birefringence. Stacking and twisting van der W…
The Topography Trap: Sifting Interlayer Excitons from Strain-Related Artifacts in Real-World 2D Hetrostructures
Pablo Hernández López, Luka Pirker, Astrid Weston +8
Novel excitonic phenomena emerging in transition metal dichalcogenide (TMDC) heterostructures belong to the most exciting topics in contemporary physics of van der Waals materials.…
Tunable magnons in a dual-gated 2D antiferromagnet
Nele Stetzuhn, Abhijeet M. Kumar, Sviatoslav Kovalchuk +12
The layered antiferromagnet CrSBr features magnons coupled to other quasiparticles, including excitons and polaritons, enabling their easy optical accessibility. In this work, we i…
Strain engineering of valley-polarized hybrid excitons in a 2D semiconductor
Abhijeet M. Kumar, Douglas J. Bock, Denis Yagodkin +11
Encoding and manipulating digital information in quantum degrees of freedom is one of the major challenges of today's science and technology. The valley indices of excitons in tran…
Excitons under large pseudomagnetic fields
Denis Yagodkin, Kenneth Burfeindt, Zakhar A. Iakovlev +7
Excitons in Transition Metal Dichalcogenides (TMDs) acquire a spin-like quantum number, a pseudospin, originating from the crystal's discrete rotational symmetry. Here, we break th…
Highly polarized single photon emitter from intrinsic localized excitons in a WSe2/CrSBr heterostructure
Varghese Alapatt, Francisco Marques-Moros, Carla Boix-Constant +4
Single photons emitters (SPEs) are key components in quantum information applications and are commonly generated in 2D materials by inhomogeneous strain engineering. Here, we repor…
Ultrafast Optical Control of Rashba Interactions in a TMDC Heterostructure
Henry Mittenzwey, Abhijeet Kumar, Raghav Dhingra +6
We investigate spin relaxation dynamics of interlayer excitons in a MoSe2/MoS2 heterostructure induced by the Rashba effect. In such a system, Rashba interactions arise from an out…
Strain activation of localized states in WSe2
Oguzhan Yücel, Denis Yagodkin, Jan N. Kirchhof +5
Single-photon emission centers generated by controlled atomic force microscopy (AFM) indentation in monolayer WSe\(_2\) on a flexible polymer substrate are explored for application…
Strain fingerprinting of exciton valley character
Abhijeet Kumar, Denis Yagodkin, Roberto Rosati +13
Momentum-indirect excitons composed of electrons and holes in different valleys define optoelectronic properties of many semiconductors, but are challenging to detect due to their…
Impact of gigahertz and terahertz transport regimes on spin propagation and conversion in the antiferromagnet IrMn
Oliver Gueckstock, Rafael L. Seeger, Tom S. Seifert +7
Control over spin transport in antiferromagnetic systems is essential for future spintronic applications with operational speeds extending to ultrafast time scales. Here, we study…
