Influence of protective layer thinning on the electrocaloric performance of 0.8Ba(Ti0.82Zr0.18)O3–0.2Ba(Ti0.9Sn0.1)O3 multilayer ceramic films

Electrocaloric Properties of Lead‐Free Multilayer Ceramic Films Composed of 0.2Ba(Ti0.9Sn0.1)O3–0.8Ba(Zr0.18Ti0.82)O3

“…This observation suggests that even at the relatively low temperature of 1270 °C, the MLEC undergoes adequate sintering, enabling successful co‐firing of the ceramic and electrode layers. [ 10 ]…”

“…This observation suggests that even at the relatively low temperature of 1270 °C, the MLEC undergoes adequate sintering, enabling successful co-firing of the ceramic and electrode layers. [10] The temperature dependence of the dielectric properties was measured at different frequencies for BZSnT20 MLECs and is shown in Figure 4. As the frequency increases, the broad peaks in the dielectric constant and loss shift to higher temperatures.…”

“…[9] Therefore, the current challenge is to achieve a large EC effect with relatively low applied voltages and enhance the field strength of the devices. [10] Extensive research has been conducted to investigate various materials for achieving a large ECE and enabling the widespread application of ferroelectric materials in refrigeration. These materials include thin films, single crystals, polycrystalline, ceramics, and polymers.…”
