With regard to the global energy crisis and environmental pollution, ferroelectric thin films
with unique polarization behavior have garnered considerable attention for energy storage …

Despite the advantages of electric field efficiency and miniaturization, the limited operating
temperature range and mediocre cooling efficiency of electrocaloric thin films represent the …

In 1880, the brothers Jacques and Pierre Curie were studying the phenomenon of
pyroelectricity. This is the effect where crystals that both lack a center-of-symmetry (ie, are …

Abstract Ba (Zr 0.2 Ti 0.8) O 3-0.5 (Ba 0.7 Ca 0.3) TiO 3 emerged as one of the most
technologically important lead-free piezoelectric compositions, and has undoubtedly shown …
