Giant negative electrocaloric effect in antiferroelectric LaDoped Pb(ZrTi)O3 thin films near room temperature

Abstract : Antiferroelectric thin films are demonstrated as a new class of giant electrocaloric materials that exhibit a negative electrocaloric response of about −5 K near room temperature. The giant negative electrocaloric effect may open up a new paradigm for light, compact, reliable, and high-efficiency refrigeration devices.
