Zeeman spectroscopy of excitons and hybridization of electronic states in few-layer WSe, MoSe and MoTe
Ashish Arora, Maciej Koperski, Artur Slobodeniuk +7
Monolayers and multilayers of semiconducting transition metal dichalcogenides (TMDCs) offer an ideal platform to explore valley-selective physics with promising applications in val…
Time-resolved magneto-Raman study of carrier dynamics in low Landau levels of graphene
Tomasz Kazimierczuk, Aleksander Bogucki, Tomasz Smoleński +5
We study the relaxation dynamics of the electron system in graphene flakes under Landau quantization regime using a novel approach of time-resolved Raman scattering. The non-resona…
Dimensional crossover of acoustic phonon lifetime in -MoSe
P. Soubelet, A. A. Reynoso, A. Fainstein +4
A time-resolved observation of coherent interlayer longitudinal acoustic phonons in 2-MoSe is reported. A femtosecond pump-probe technique is used to investigate the evoluti…
Fine structure of -excitons in multilayers of transition metal dichalcogenides
A. O. Slobodeniuk, Ł. Bala, M. Koperski +8
Reflectance and magneto-reflectance experiments together with theoretical modelling based on the approach have been employed to study the evolution of direct ba…
Valley polarization of exciton-polaritons in monolayer WSe2 in a tunable microcavity
M. Król, K. Lekenta, R. Mirek +8
Monolayer transition metal dichalcogenides, known for exhibiting strong excitonic resonances, constitute a very interesting and versatile platform for investigation of light-matter…
Tuning carrier concentration in a superacid treated MoS monolayer
Maciej R. Molas, Katarzyna Gołasa, Łukasz Bala +4
The effect of bis(trifluoromethane) sulfonimide (TFSI, superacid) treatment on the optical properties of MoS monolayers is investigated by means of photoluminescence, reflectan…
