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…
Electronic and spectral properties of Ge1-xSnx quantum dots: an atomistic study
Krzysztof Gawarecki, Jakub Ziembicki, Paweł Scharoch +1
In this paper, we study theoretically the electron and spectral properties of Ge1-xSnx systems, including alloys, cubic- and spherical quantum dots. The single-particle electron an…
Invariant expansion of the 30-band k.p model and its parameters for III-V compounds
Krzysztof Gawarecki, Paweł Scharoch, Michał Wiśniewski +4
In this work we derive a ready-to-use symmetry invariant expansion of the full-zone 30-band k.p Hamiltonian for the Td point group. In order to find respective parameters, the band…
