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…
Resonant Raman scattering in bilayer 3R-MoS
Chinmay K. Mohanty, Kacper Walczyk, Tomasz Woźniak +5
Raman scattering is a powerful spectroscopic technique widely employed to investigate light-matter interactions and lattice dynamics in two-dimensional materials. Here, we investig…
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…
Strong Spin-Lattice Interaction in Layered Antiferromagnetic CrCl
Åucja Kipczak, Tomasz Woźniak, Chinmay K. Mohanty +10
Understanding the coupling between lattice vibrations and magnetic order is crucial for controlling properties of two-dimensional magnetic materials. Here, we investigate the vibra…
Raman scattering fingerprints of the charge density wave state in one-dimensional NbTe
Natalia Zawadzka, Cem Sevik, Zahir Muhammad +4
Charge-density waves (CDWs) are ordered quantum states of conduction electrons accompanied by periodic lattice distortions. Raman scattering (RS) spectroscopy is therefore well sui…
Fast Interlayer Energy Transfer from the Lower Bandgap MoS2 to the Higher Bandgap WS2
Gayatri, Mehdi Arfaoui, Debashish Das +9
Energy transfer (ET) is a dipole-dipole interaction, mediated by the virtual photon. Traditionally, ET happens from the higher (donor) to lower bandgap (acceptor) material. However…
