Photoluminescence efficiency of MBE-grown MoSe monolayers featuring sharp excitonic lines and diverse grain structures
Mateusz Raczyński, Julia Kucharek, Kacper Oreszczuk +7
Recent studies have demonstrated that using h-BN as a substrate for the growth of transition metal dichalcogenides can significantly reduce excitonic linewidths. However, many othe…
Hybrid electroluminescence device for on-demand single photon generation at room temperature
Aleksander Rodek, Mateusz Hajdel, Kacper Oreszczuk +6
Recent research focused on single photon emitters (SPEs) hosted by layered semiconductors, particularly hexagonal boron nitride (hBN), has revealed a promising alternative to quant…
Hybrid electroluminescent devices composed of (In,Ga)N micro-LEDs and monolayers of transition metal dichalcogenides
K. Oreszczuk, J. Slawinska, A. Rodek +3
We demonstrate a novel electro-luminescence device in which GaN-based -LEDs are used to trigger the emission spectra of monolayers of transition metal dichalcogenides, which are…
Excitonic complexes in -doped WS monolayer
M. Zinkiewicz, T. Woźniak, T. Kazimierczuk +12
We investigate the origin of emission lines apparent in the low-temperature photoluminescence spectra of -doped WS monolayer embedded in hexagonal BN layers using external m…
Neutral and charged dark excitons in monolayer WS
M. Zinkiewicz, A. O. Slobodeniuk, T. Kazimierczuk +12
Low temperature and polarization resolved magneto-photoluminescence experiments are used to investigate the properties of dark excitons and dark trions in a monolayer of WS enc…
Temperature dependence of photoluminescence lifetime of atomically thin WSe2 layer
Aleksandra Łopion, Mateusz Goryca, Tomasz Smoleński +5
At cryogenic temperatures, the photoluminescence spectrum of monolayer WSe2features a num-ber of lines related to the recombination of so-called localized excitons. The intensity o…
Probing and manipulating valley coherence of dark excitons in monolayer WSe
M. R. Molas, A. O. Slobodeniuk, T. Kazimierczuk +10
Monolayers of semiconducting transition metal dichalcogenides are two-dimensional direct-gap systems which host tightly-bound excitons with an internal degree of freedom correspond…
Origin of luminescence quenching in structures containing CdSe/ZnSe quantum dots with a few Mn ions
Kacper Oreszczuk, Mateusz Goryca, Wojciech Pacuski +3
We present a detailed spectroscopic study of the photoluminescence quenching in an epitaxial structures containing CdSe/ZnSe quantum dots doped with low concentration of Mn…
Comparison of magneto-optical properties of various excitonic complexes in CdTe and CdSe self-assembled quantum dots
J. Kobak, T. Smoleński, M. Goryca +13
We present a comparative study of two self-assembled quantum dot (QD) systems based on II-VI compounds: CdTe/ZnTe and CdSe/ZnSe. Using magneto-optical techniques we investigated a…
