Domain‐Wall Driven Suppression of Thermal Conductivity in a Ferroelectric Polycrystal

Abstract A common strategy for reducing the thermal conductivity of polycrystalline systems is to increase the number of grain boundaries. Indeed, grain boundaries enhance the probability of phonon scattering events, which has been applied to control the thermal transport in a wide range of material...
