Engineering the hole confinement for CdTe-based quantum dot molecules
Ł. Kłopotowski, P. Wojnar, S. Kret +4
We demonstrate an efficient method to engineer the quantum confinement in a system of two quantum dots grown in a vertical stack. We achieve this by using materials with a differen…
Optical signatures of spin dependent coupling in semimagnetic quantum dot molecules
Ł. Kłopotowski, P. Wojnar, Ł. Cywiński +5
We present photoluminescence studies of CdTe and CdMnTe quantum dots grown in two adjacent layers. We show that when the dots are 8 nm apart, their magnetooptical properties - Zeem…
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…
Influence of exciton spin relaxation on the photoluminescence spectra of semimagnetic quantum dots
Ł. Kłopotowski, Ł. Cywiński, M. Szymura +8
We present a comprehensive experimental and theoretical studies of photoluminescence of single CdMnTe quantum dots with Mn content x ranging from 0.01 to 0.2. We distinguish three…
Quantum interference in exciton-Mn spin interactions in a CdTe semiconductor quantum dot
A. Trojnar, M. Korkusinski, E. Kadantsev +6
We show theoretically and experimentally the existence of a new quantum interference(QI) effect between the electron-hole interactions and the scattering by a single Mn impurity. T…
Brightening of dark excitons in a single quantum dot containing a single magnetic ion
M. Goryca, P. Plochocka, T. Kazimierczuk +5
A promising method to investigate dark exciton transitions in quantum dots is presented. The optical recombination of the dark exciton is allowed when the exciton state is coupled…
