Tunable Magneto-Excitonic Coupling in Alloyed van der Waals Antiferromagnet
Maciej Smiertka, Oliwia Janikowska, Katarzyna Olkowska-Pucko +18
The unique coupling between magnetic order and photo-generated excitons, electron-hole pairs bound by Coulomb interaction, in layered magnetic semiconductors offers a powerful mech…

Distinct Magneto-Optical Response of Frenkel and Wannier Excitons in CrSBr
Maciej Smiertka, Michal Rygala, Katarzyna Posmyk +10
This study shows that CrSBr hosts Frenkel-like and Wannier-Mott-like excitons whose distinct spatial character explains their contrasting sensitivity to magnetic order and lattice…

Phonon-bottleneck enhanced exciton emission in 2D perovskites
Joshua J. P. Thompson, Mateusz Dyksik, Paulina Peksa +8
Layered halide perovskites exhibit remarkable optoelectronic properties and technological promise, driven by strongly bound excitons. The interplay of spin-orbit and exchange coupl…
