Light-hole states and hyperfine interaction in electrically-defined Ge/GeSn quantum dots

Agnieszka Miętkiewicz, Jakub Ziembicki, Krzysztof Gawarecki

We theoretically investigate hole spins confined in a gate-defined quantum dot (QD) embedded in GeSn/Ge/GeSn quantum well (QW) structure. Owing to the tensile strain in the Ge laye…

Modeling the g-factors, hyperfine interaction and optical properties of semiconductor QDs: the atomistic and eight-band $k \cdot p$ approaches

Krzysztof Gawarecki, Alina Garbiec, Jakub Stanecki +1

We present a detailed comparative study of two important theoretical approaches: atomistic sp $^{3}$ d $^{5}$ s $^{*}$ tight-binding and continuum eight-band $k \cdot p$ methods, for modeling…
