Mechanisms of optical orientation of an individual Mn ion spin in a II-VI quantum dot
T. Smoleński, Ł. Cywiński, P. Kossacki
We provide a theoretical description of the optical orientation of a single Mn ion spin under quasi-resonant excitation demonstrated experimentally by Goryca et al. [Phys. R…
Fine structure of an exciton coupled to a single Fe2+ ion in a CdSe/ZnSe quantum dot
T. Smoleński, T. Kazimierczuk, M. Goryca +2
We present a polarization-resolved photoluminescence study of the exchange interaction effects in a prototype system consisting of an individual Fe2+ ion and a single neutral excit…
Direct determination of zero-field splitting for single Co ion embedded in a CdTe/ZnTe quantum dot
J. Kobak, A. Bogucki, T. Smoleński +6
When Co impurity is embedded in semiconductor structure, crystal strain strongly influences zero-filed splitting between Co states with spin projection $S_z = \pm 3/2…
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…
Epitaxial growth and Photoluminescence Excitation spectroscopy of CdSe Quantum Dots in (Zn,Cd)Se barrier
J. Piwowar, W. Pacuski, T. Smoleński +6
Design, epitaxial growth, and resonant spectroscopy of CdSe Quantum Dots (QDs) embedded in an innovative (Zn,Cd)Se barrier are presented. The (Zn,Cd)Se barrier enables shifting of…
Efficient injection of spin-polarized excitons and optical spin orientation of a single Mn2+ ion in a CdSe/ZnSe quantum dot
T. Smoleński, W. Pacuski, M. Goryca +3
Circularly polarized optical excitation is used to demonstrate the efficient injection of spin-polarized excitons to individual self-assembled CdSe quantum dots in ZnSe barrier. Th…
Coherent precession of an individual 5/2 spin
M. Goryca, M. Koperski, P. Wojnar +4
We present a direct observation of a coherent spin precession of an individual Mn ion, having both electronic and nuclear spins equal to 5/2, embedded in a CdTe quantum dot…
Introducing single Mn2+ ions into spontaneously coupled quantum dot pairs
M. Koperski, M. Goryca, T. Kazimierczuk +4
We present the photoluminescence excitation study of the self-assembled CdTe/ZnTe quantum dots doped with manganese ions. We demonstrate the identification method of spontaneously…
