Size dependence of biexciton binding energy in strained ZnTe/(Zn,Mg)Te nanowire quantum dots
P. Baranowski, M. Zielinski, M. Szymura +6
Nanowire quantum dots, i.e., heterostructures consisting of an axial insertion of low bandgap semiconductor within large band gap semiconductor nanowire, attract interest due to th…
Carrier separation in type II quantum dots inserted in (Zn,Mg)Te/ZnSe nanowire
P Baranowski, M. Szymura, M. Wojcik +6
Quantum dots consisting of an axial Zn0.97Mg0.03Te insertion inside a large bandgap Zn0.9Mg0.1Te nanowire cores are fabricated in a molecular beam epitaxy system by employing the v…
Reconstruction of three-dimensional strain field in an asymmetrical curved core-shell hetero-nanowire
Serhii Kryvyi, Slawomir Kret, Piotr Wojnar
Crystal orientation and strain mapping of an individual curved and asymmetrical core-shell hetero-nanowire is performed based on transmission electron microscopy. It relies on a co…
Excitonic fine structure of epitaxial Cd(Se,Te) on ZnTe type-II quantum dots
Petr Klenovský, Piotr Baranowski, Piotr Wojnar
The structure of the ground state exciton of Cd(Se,Te) quantum dots embedded in ZnTe matrix is studied experimentally using photoluminescence spectroscopy and theoretically using $…
Near-infrared emission from spatially indirect excitons in type II ZnTe/CdSe/(Zn,Mg)Te core/double-shell nanowires
Piotr Wojnar, Jakub Plachta, Anna Reszka +9
ZnTe/CdSe/(Zn,Mg)Te core/double-shell nanowires are grown by molecular beam epitaxy by employing the vapor-liquid-solid growth mechanism assisted with gold catalysts. A photolumine…
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…
