Article Synopsis
- Formamidinium-based halide perovskite crystals exhibit unique properties compared to methylammonium-based ones, due to their inorganic sublattice having local static disorder while maintaining an overall average structure.
- The researchers utilized terahertz-range Raman scattering, single-crystal X-ray diffraction, and first-principles calculations to investigate how the dynamics of the inorganic sublattice change with temperature from 10 to 300 K.
- The findings indicate that low-temperature local static disorder significantly influences the crystal structure and phase changes as the temperature increases.
