Hydrostatic Pressure Driven Band Gap Tuning and Self-Trapped Exciton Formation in (4FPEA)SnBr Halide Perovskite
Rafał Bartoszewicz, Jakub Ziembicki, Ewelina Zdanowicz +5
Two-dimensional tin halide perovskites provide a highly tunable platform for exciton phonon coupling and local lattice distortions, enabled by their intrinsically soft lattice. We…
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…
Linear dichroism of the optical properties of SnS and SnSe van der Waals crystals
Agata K. Tołłoczko, Jakub Ziembicki, Miłosz Grodzicki +6
Tin monochalcogendies SnS and SnSe, belonging to a familiy of van der Waals crystals isoelectronic to black phosphorus, are know as enivornmetally-friendly materials promisng for t…
Electronic and structural properties of group IV materials and their polytypes
Jakub Ziembicki, Paweł Scharoch, Maciej P. Polak +2
Nanotechnology's impact on semiconductor industry advancement, particularly through the engineering of nanostructures like nanowires, opens new possibilities for material functiona…
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…
