Probing the inter-layer exciton physics in a MoS/MoSe/MoS van der Waals heterostructure
M. Baranowski, A. Surrente, L. Klopotowski +9
Stacking atomic monolayers of semiconducting transition metal dichalcogenides (TMDs) has emerged as an effective way to engineer their properties. In principle, the staggered band…
Onset of exciton-exciton annihilation in single layer black phosphorus
A. Surrente, A. A. Mitioglu, K. Galkowski +5
The exciton dynamics in monolayer black phosphorus is investigated over a very wide range of photoexcited exciton densities using time resolved photoluminescence. At low excitation…
Magneto-excitons in large area CVD grown monolayer MoS and MoSe on sapphire
A. A. Mitioglu, K. Galkowski, A. Surrente +5
Magneto transmission spectroscopy was employed to study the valley Zeeman effect in large-area monolayer MoS and MoSe. The extracted values of the valley g-factors for…
Intervalley scattering of excitons and trions in monolayer WSe under strong excitation
A. A. Mitioglu, L. Klopotowski, D. K. Maude +4
Monolayer transition metal dichalcogenides offer the possibility of optical control of the valley degree of freedom. In order to asses the potential of these materials in applicati…
In-plane radiative recombination channel of a dark exciton in self-assembled quantum dots
Tomasz Smoleński, Tomasz Kazimierczuk, Mateusz Goryca +6
We demonstrate evidence for a radiative recombination channel of dark excitons in self-assembled quantum dots. This channel is due to a light hole admixture in the excitonic ground…
Magnetic polaron formation and exciton spin relaxation in single CdMnTe quantum dots
Łukasz Kłopotowski, Łukasz Cywiński, Piotr Wojnar +8
We study the formation dynamics of a spontaneous ferromagnetic order in single self-assembled CdMnTe quantum dots. By measuring time-resolved photoluminescence, we determine the fo…
