Highly reversible extrinsic electrocaloric effects over a wide temperature range in epitaxially strained SrTiO3 films

Nature Materials, Published online: 21 March 2024; doi:10.1038/s41563-024-01831-1

Electrocaloric effects are large in a limited set of materials that display hysteretic first-order phase transitions. Here epitaxial SrTiO3 thin films are strain engineered to achieve anhysteretic second-order phase transitions, with electrocaloric effects enhanced by one order of magnitude over bulk.Nature Materials, Published online: 21 March 2024; doi:10.1038/s41563-024-01831-1Electrocaloric effects are large in a limited set of materials that display hysteretic first-order phase transitions.
