Kondo-like phonon scattering in thermoelectric clathrates, Published online: 21 February 2019; doi:10.1038/s41467-019-08685-1

Thermoelectric clathrates host guest atoms that can rattle inside their surrounding cages, yielding unusual phononic properties. Ikeda et al. show that ab initio calculations fail to account for thermodynamic and thermal transport data and propose a Kondo-like mechanism to explain the discrepancy.
