Ultralow Lattice Thermal Conductivity and Large Glass‐Like Contribution in Cs3Bi2I6Cl3: Rattling Atoms and p‐Band Electrons Driven Dynamic Rotation

Ultralow Lattice Thermal Conductivity and Large Glass‐Like Contribution in Cs3Bi2I6Cl3: Rattling Atoms and p‐Band Electrons Driven Dynamic Rotation

Abstract Understanding the origin of ultralow lattice thermal conductivity κL of halide perovskites is of great significance in the energy conversion field. The soft phonon modes and the large anharmonicity corresponding to the dynamic rotation of halogen atoms play an important role in limiting the...
