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…
Mapping of quantum well eigenstates with semimagnetic probes
Ł. Kłopotowski, A. Gruszczyńska, E. Janik +4
We present results of transmission measurements on CdTe quantum wells with thin semimagnetic CdMnTe probe layers embedded in various positions along the growth axis. The presence o…
Optical Anisotropy and Pinning of the Linear Polarization of Light in Semiconductor Microcavities
L. Klopotowski, M. D. Martin, A. Amo +6
We report a strong experimental evidence of the optical anisotropy in a CdTe-based microcavity: the polarization of light is pinned to one of the crystallographic axes independentl…
