Hydrostatic Pressure Driven Band Gap Tuning and Self-Trapped Exciton Formation in (4FPEA)SnBr Halide Perovskite
RafaÅ 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 MiÄtkiewicz, 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…
