Low-dimensional van der Waals semiconductors with reduced symmetry provide a unique platform for exploring anisotropic physical properties. The quasi-one-dimensional family MXQ…
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…
Dopant-induced modifications of the optical properties of GaSe
Jakub Sójka, Katarzyna Olkowska-Pucko, Kacper Walczyk +5
Doping plays a crucial role in tailoring the electronic, optical, and magnetic properties of semiconductors, enabling control of carrier dynamics and the formation of functional st…
Doping-Induced Brightening of Dark Excitons and Trions in a WSe Monolayer
Grzegorz Krasucki, Artur O. Slobodeniuk, Kacper Walczyk +5
Optically dark excitonic states play a critical role in the valleytronic, electronic, and optical properties of monolayer semiconducting transition metal dichalcogenides. Here, we…
Spin-phonon coupling and isotope-related pseudo-molecule vibrations in layered CrGeTe ferromagnet
Grzegorz Krasucki, Katarzyna Olkowska-Pucko, Tomasz Woźniak +4
The vibrational structure of chromium germanium telluride (CrGeTe, CGT) is investigated and a strong spin-phonon coupling is revealed. The measured high-resolution Rama…
Extremely high excitonic -factors in 2D crystals by alloy-induced admixing of band states
Katarzyna Olkowska-Pucko, Tomasz Woźniak, Elena Blundo +24
Monolayers (MLs) of semiconducting transition metal dichalcogenides (\mbox{S-TMDs}) emit light very efficiently and display rich spin-valley physics, with gyromagnetic (-) facto…
Optical response of WSe-based vertical tunneling junction

Layered materials have attracted significant interest because of their unique properties. Van der Waals heterostructures based on transition-metal dichalcogenides have been extensi…
Localisation-to-delocalisation transition of moiré excitons in WSe/MoSe heterostructures
Elena Blundo, Federico Tuzi, Salvatore Cianci +12
Moiré excitons (MXs) are electron-hole pairs localised by the periodic (moiré) potential forming in two-dimensional heterostructures (HSs). MXs can be exploited, , for creati…
Analogy and dissimilarity of excitons in monolayer and bilayer of MoSe
Łucja Kipczak, Artur O. Slobodeniuk, Tomasz Woźniak +8
Excitons in thin layers of semiconducting transition metal dichalcogenides are highly subject to the strongly modified Coulomb electron-hole interaction in these materials. Therefo…
Excitonic luminescence of iodine-intercalated HfS
