演講摘要:
Halide perovskites exhibit remarkable optoelectronic properties, with their phonon transport playing a pivotal role in determining thermal conductivity, carrier dynamics, and device performance. This talk will focus on their unique and exceptionally low thermal conductivity, which arises from soft lattice vibrations and the inherent complexity of their dynamic structures. Key phonon scattering mechanisms, including anharmonicity, dynamic ion migration, and acoustic-optical phonon coupling, will be thoroughly discussed. Associated temperature-dependent lattice dynamics will also be explored, with particular emphasis on the distinctive crystal-liquid duality observed in organic-inorganic halide perovskites.
