## Description

- description: Finding routes to achieve ultralow lattice thermal conductivity is
    vital for advanced thermal functional materials. Cheng et al. demonstrate that
    partial Cu occupancy and moderate atomic hopping in Cu4TiSe4 create intense phonon
    scattering without opening a convection channel, bridging fully rigid lattices
    and liquid-like superionic states to achieve a drastic suppression of thermal
    transport.
