Electronic and spectral properties of Ge1-xSnx quantum dots: an atomistic study

Autor: Gawarecki, Krzysztof, Ziembicki, Jakub, Scharoch, Paweł, Kudrawiec, Robert

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 and hole states are calculated within the sp3d5s* tight-binding approach

Invariant expansion of the 30-band k.p model and its parameters for III-V compounds

Autor: Gawarecki, Krzysztof, Scharoch, Paweł, Wiśniewski, Michał, Ziembicki, Jakub, Mączko, Herbert S., Gładysiewicz, Marta, Kudrawiec, Robert

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 structures of III-V materials were calculated within a state-of-the-a
