Large enhancement of the electrocaloric effect in PLZT ceramics prepared by hot-pressing

APL Materials, 2016
In this contribution, we demonstrate the optimization of the microstructures of the Pb0.85La0.1(Zr0.65Ti0.35)O3 (PLZT) relaxor ferroelectric ceramics and subsequent enhancements in their polarization and electrical resistivity by using a hot-pressing ...

Ultralow operating voltage for energy conversion performance in Hf1–xZrxO2 thin films

Journal of Materiomics
Emerging ferroelectric and antiferroelectric HfO2-based thin films are attractive candidates for energy conversion and storage applications. In this work, the polar phase transformation between tetragonal and orthorhombic phases associated with ...

Electrocaloric effects at a phase transition created by strain

Nature Materials
Electrocaloric effects have not hitherto been experimentally studied at a phase transition created by strain. It is now shown that the continuous transition created by epitaxial strain in strontium titanate films greatly enhances electrocaloric effects over a wide range of temperatures, including room temperature.
