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…
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 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…
