Some strategies for improving caloric responses with ferroelectrics
Résumé
Many important breakthroughs and significant engineering developments have been
achieved during the past two decades in the field of caloric materials. In this review,
we address ferroelectrics emerging as ideal materials which permit both giant
elastocaloric and/or electrocaloric responses near room temperature. We summarize
recent strategies for improving caloric responses using geometrical optimization,
maximizing the number of coexisting phases, combining positive and negative caloric
responses, introducing extra degree of freedom like mechanical stress/pressure, and
multicaloric effect driven by either single stimulus or multiple stimuli. This review
highlights the promising perspective of ferroelectrics for developing next-generation
solid-state refrigeration.
