Lead-free (Ba,Ca)(Zr,Ti)O3 Based Electrocaloric Devices: Challenges and Perspectives
Published online by Cambridge University Press: 17 July 2013
Abstract
In this work, we analyze the requirement to (Ba,Ca)(Zr,Ti)O3 thin films for applications in electrocaloric devices. We demonstrate that large temperature changes are realized mostly independent of the used material by applying sufficient electric fields. Ferroelectrics exhibiting a diffuse phase transition are beneficial for electrocaloric applications, but they change the range of operational temperatures.
