Electron g-factor in nanostructures: continuum media and atomistic approach
Krzysztof Gawarecki, Michał Zieliński
We report studies of -dependent Landé -factor, performed by both continuous media approximation k.p method, and atomistic tight-binding spds approach. We propose…
Phonon-assisted relaxation between triplet and singlet states in a self-assembled double quantum dot
Krzysztof Gawarecki, Paweł Machnikowski
We study theoretically phonon-induced spin dynamics of two electrons confined in a self-assembled double quantum dot. We calculate the transition rates and time evolution of occupa…
Hole spin-flip transitions in a self-assembled quantum dot
Mateusz Krzykowski, Krzysztof Gawarecki, Pawel Machnikowski
In this work, we investigate hole spin-flip transitions in a single self-assembled InGaAs/GaAs quantum dot. We find the hole wave functions using the 8-band model and calculat…
The importance of second order deformation potentials in modeling of InAs/GaAs nanostructures
Krzysztof Gawarecki, Michał Zieliński
Accurate modeling of electronic properties of nanostructures is a challenging theoretical problem. Methods making use of continuous media approximation, such as k.p, sometimes stru…
Interplay between emission wavelength and s-p splitting in MOCVD-grown InGaAs/GaAs quantum dots emitting above 1.3 μm
Paweł Podemski, Anna Musiał, Krzysztof Gawarecki +11
The electronic structure of strain-engineered single InGaAs/GaAs quantum dots emitting in the telecommunication O band is probed experimentally by photoluminescence excitation spec…
Hyperfine interaction for holes in quantum dots: k.p model
Paweł Machnikowski, Krzysztof Gawarecki, Łukasz Cywiński
We formulate the multi-band kp theory of hyperfine interactions for semiconductor nanostructures in the envelope function approximation. We apply this theoretical description to th…
