Enhanced electrocaloric strength in P(VDF-TrFE-CFE) by decreasing the crystalline size

Journal of Materiomics, 2019
Through the modulation of the dipolar entropy under an applied electric field (E), a reversible temperature change (ΔT) could be achieved in a dielectric material, which is known as the electrocaloric (EC) effect.

Composition dependence of giant electrocaloric effect in PbxSr1-xTiO3 ceramics for energy-related applications

Journal of Materiomics, 2019
PbxSr1-xTiO3 (x = 0.30, 0.35, 0.40, 0.45, 0.50 and 0.55) ceramics were fabricated by a solid-state reaction route. X–ray diffraction data at room temperature show PST samples shift from cubic to tetragonal phase with the increase of Pb2+ content.

Enhancement of electrocaloric response through quantum effects

Physical Review B, 2017
A semiclassical approach that incorporates quantum mechanical behavior of heat capacity in direct caloric effect simulations is proposed. Application of this methodology to study electrocaloric effect in prototypical ferroelectrics ${ \rm PbTiO_3 }$, and ${ \rm BaTiO_3 }$, reveals severe underestimation of electrocaloric response at lowest temperatures
