Domain-wall driven suppression of thermal conductivity in a ferroelectric polycrystal
Rachid Belrhiti-Nejjar, Manuel Zahn, Patrice Limelette +8
A common strategy for reducing thermal conductivity of polycrystalline systems is to increase the number of grain boundaries. Indeed, grain boundaries enhance the probability of ph…

Lead-free room-temperature ferroelectric thermal conductivity switch using anisotropies in thermal conductivities
Lucile Féger, Carlos Escorihuela-Sayalero, Jean-Michel Rampnoux +11
Materials with on-demand control of thermal conductivity are the prerequisites to build thermal conductivity switches, where the thermal conductivity can be turned ON and OFF. Howe…
