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…
Polariton lasing in high-quality Selenide-based micropillars in the strong coupling regime
T. Klein, S. Klembt, E. Durupt +3
We have designed and fabricated all-epitaxial ZnSe-based optical micropillars exhibiting the strong coupling regime between the excitonic transition and the confined optical cavity…
Exciton-polaritons gas as a nonequilibrium coolant
Sebastian Klembt, Emilien Durupt, Sanjoy Datta +7
Using angle-resolved Raman spectroscopy, we show that a resonantly excited ground-state exciton-polariton fluid behaves like a nonequilibrium coolant for its host solid-state semic…
Determination of the Fermi Level Position in Dilute Magnetic GaMnN Films
Stefan Barthel, Gerd Kunert, Mariuca Gartner +6
We report on a combined theoretical and experimental determination of the Fermi level position in wurtzite GaMnN films with and as grown by molecular…
Phase diagram and critical behavior of the random ferromagnet
S. Stefanowicz, G. Kunert, C. Simserides +11
Molecular beam epitaxy has been employed to obtain Ga1-xMnxN films with x up to 10% and Curie temperatures T_C up to 13 K. The magnitudes of T_C and their dependence on x, T_C(x) ~…
Pronounced Purcell enhancement of spontaneous emission in CdTe/ZnTe quantum dots embedded in micropillar cavities
Tomasz Jakubczyk, Wojciech Pacuski, Tomasz Smoleński +6
The coupling of CdTe/ZnTe quantum dot (QD) emission to micropillar cavity eigenmodes in the weak coupling regime is demonstrated. We analyze photoluminescence spectra of QDs embedd…
