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…
Directed light emission from monolayers on 2D materials via optical interferences
Pavel Trofimov, Sabrina Juergensen, Adrián Dewambrechies Fernández +3
Two-dimensional materials provide a rich platform to explore phenomena such as emerging electronic and excitonic states, strong light-matter coupling and new optoelectronic device…
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…
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…
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…
