Their light\u2010to\u2010electricity or thermal\u2010to\u2010electricity conversion is strongly determined by the dynamics of the corresponding lattice vibrations. Here, the measurement of lattice dynamics is presented in a prototypical lead\u2010free halide double perovskite(Cs<jats:sub>2<\/jats:sub>NaInCl<jats:sub>6<\/jats:sub>). The quantitative measurements and first\u2010principles calculations show that the scatterings among lattice vibrations at room temperature are at the timescale of \u22481\u00a0ps, which stems from the extraordinarily strong anharmonicity in Cs<jats:sub>2<\/jats:sub>NaInCl<jats:sub>6<\/jats:sub>. Further the degree of anharmonicity of each type of atom is quantitatively characterized in the Cs<jats:sub>2<\/jats:sub>NaInCl<jats:sub>6<\/jats:sub> single crystal, which stems from the interatomic forces, and demonstrate that this strong anharmonicity is synergistically contributed by the bond hierarchy, the tilting of the NaCl<jats:sub>6<\/jats:sub> and InCl<jats:sub>6<\/jats:sub> octahedral units, and the rattling of Cs<jats:sup>+<\/jats:sup> ions. Consequently, the crystalline Cs<jats:sub>2<\/jats:sub>NaInCl<jats:sub>6<\/jats:sub> possesses an ultralow thermal conductivity of \u22480.43\u00a0W\u00a0mK<jats:sup>\u22121<\/jats:sup> at room temperature, and a weak temperature dependence of <jats:italic>T<\/jats:italic>\n<jats:sup>\u22120.41<\/jats:sup>. These findings uncovered the underlying mechanisms behind the dynamics of lattice vibrations in double perovskites, which can largely benefit the design of optoelectronics and thermoelectrics based on halide double perovskites.<\/jats:p>","DOI":"10.1002\/advs.202408149","type":"journal-article","created":{"date-parts":[[2025,1,21]],"date-time":"2025-01-21T02:09:21Z","timestamp":1737425361000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Observation
