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…
Magnetic-field-induced abrupt spin state transition in a quantum dot containing magnetic ions
Maciej Koperski, Tomasz Smoleński, Mateusz Goryca +3
We present the results of a comprehensive magneto-optical characterization of single CdTe quantum dots containing a few Mn2+ ions. We find that some quantum dots exhibit an unexpec…
Tuning valley polarization in a WSe2 monolayer with a tiny magnetic field
T. Smoleński, M. Goryca, M. Koperski +5
In monolayers of semiconducting transition metal dichalcogenides, the light helicity ( or ) is locked to the valley degree of freedom, leading to the possibility of optic…
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…
Designing quantum dots for solotronics
J. Kobak, T. Smoleński, M. Goryca +11
Solotronics, optoelectronics based on solitary dopants, is an emerging field of research and technology reaching the ultimate limit of miniaturization. It aims at exploiting quantu…
Picosecond charge variation of quantum dots under pulsed excitation
Tomasz Kazimierczuk, Mateusz Goryca, Maciej Koperski +5
We present a spectroscopic study of excitation dynamics in self assembled CdTe/ZnTe quantum dots. Insight into details of kinetics is obtained from the time resolved micro-photolum…
