Advanced Science, EarlyView.Unraveling the underlying mechanisms at the origin of ultra‐low thermal conductivity in pristine crystals is of central relevance to designing new functional materials. Single crystals of the candidate functional material BaBiO3 show an anomalous glassy thermal conductivity, which reveals the role of strong anharmonicity and additional scattering ...

Advanced Science, EarlyView.The bonding hierarchy in X6Re6S8I8 (X = Rb, Cs) promotes phonon localization, generating extensive discrete phonon flat bands that redefine the lower bounds of lattice thermal conductivity in crystals. Abstract Within the unified theoretical framework for thermal transport, the inherent interplay between coherent tunneling and propagative phonon ...
