Although gap-based and liquid-based thermal switches that work on the basis of mechanical movements have been an effective approach to control the flow of heat in the devices, their complex mechanisms impose considerable costs in latency, expense, and power consumption. As a consequence, materials that have multiple solid-state phases with distinct thermal properties are appealing for thermal management due to their simplicity, fast switching, and compactness. Thus, an ideal thermal switch should operate near or above room temperature, have a simple trigger mechanism, and offNature communicationsObservation of solid-state bidirectional thermal conductivity switching in antiferroelectric lead zirconate (PbZrO₃).PMC8943065W911NF-21-1-0118Aryana KPfeifer TWBraun JLOlson DHNag JMimura TOpila EJMartin LWHowe JMHopkins PETomko JAGao RSalanova AHoque MSBIhlefeld JFMakarem SRead JCHoglund ERfalseObservation of solid-state bidirectional thermal conductivity switching in antiferroelectric lead zirconate (PbZrO₃).Materials with tunable thermal properties enable on-demand control of temperature and heat flow, which is an integral component in the development of solid-state refrigeration, energy scavenging, and thermal circuits.
