Tailoring the electrocaloric effect by internal bias fields and field protocols
Yang-Bin Ma, Bai-Xiang Xu, Karsten Albe +1
In acceptor doped ferroelectrics and in ferroelectric films and nanocomposites, defect dipoles, strain gradients, and the electric boundary conditions at interfaces and surfaces of…
Determination of optimal reversed field with maximal electrocaloric cooling by a direct entropy analysis
Yang-Bin Ma, Nikola Novak, Karsten Albe +1
Application of a negative field on a positively poled ferroelectric sample can enhance the electrocaloric cooling and appears as a promising method to optimize the electrocaloric c…
State transition and electrocaloric effect of BaZrTiO: simulation and experiment
Yang-Bin Ma, Christian Molin, Vladimir V. Shvartsman +4
The electrocaloric effect (ECE) of BaZrTiO (BZT) is closely related to the relaxor state transition of the materials. This work presents a systematic study on the…
Enhancement of the electrocaloric cooling by electric field reversal: simulation and experiment
Yang-Bin Ma, Nikola Novak, Jurij Koruza +3
An improved thermodynamic cycle is proposed, where the cooling effect of an electrocaloric refrigerant is enhanced by applying a reversed electric field. In contrast to conventiona…
Positive and negative electrocaloric effect in BaTiO in the presence of defect dipoles
Yang-Bin Ma, Anna Grünebohm, Kai-Christian Meyer +2
The influence of defect dipoles on the electrocaloric effect (ECE) in acceptor doped BaTiO is studied by means of lattice-based Monte-Carlo simulations. A Ginzburg-Landau type…
