Hydrostatic Pressure Driven Band Gap Tuning and Self-Trapped Exciton Formation in (4FPEA)${}_2$SnBr${}_4$ 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…
