Vibrational properties differ between halide and chalcogenide perovskite semiconductors, and it matters for optoelectronic performance

K. Ye, M. Menahem, T. Salzillo +7

We report a comparative study of temperature-dependent photoluminescence and structural dynamics of two perovskite semiconductors, the chalcogenide BaZrS${}_3$ (BZS) and the halide C…
