This project has the capacity to deliver revolutionary technology for a wide range of refrigeration and/or power generation scenarios.Our discovery paper [AS Mischenko, Q Zhang, JF Scott, RW Whatmore & ND Mathur, Science 311 (2006) 1270] marks the rebirth of a field of research but it is only a materials development and we do not yet know whether any technology will actually result.The point of this grant application is to develop materials that function well near room temperature, and demonstrate refrigeration and electricity generation in devices. Moreover, this proposal contains a strong scientific component that will reveal new information about electrocaloric materials and the way they behave.The materials development is perfectly realistic because the electrocaloric effect is expected near any ferroelectric phase transition, and there are many suitable materials such as those we name explicitly. Moreover, the strategies we propose for improving properties of interest are well established.The device fabrication, which is relatively straightforward, is necessary since our promising simulation efforts [AS Mischenko & ND Mathur, GB Patent 2420662 (2006)] are no substitute for real data. Note that there are several aspects to device optimisation, e.g. film thickness and composition.

该项目有能力为广泛的制冷和/或发电方案提供革命性技术。研究领域的重生，但这只是材料的开发，我们尚不知道是否会真正产生任何技术。该赠款应用的目的是开发靠近室温的材料，并在设备。此外，该提案包含一个强大的科学组成部分，它将揭示有关电源材料及其行为方式的新信息。材料的开发是完全现实的，因为在任何铁电相变附近都可以进行电静电效应，并且有许多合适的材料，例如这些材料，例如我们明确命名。此外，我们提出的改善感兴趣属性的策略已经建立了很好的确定。由于我们有希望的仿真工作[Mischenko＆nd Mathur，GB Patent 2420662（2006）]，这是相对简单的，这是相对简单的，这是相对简单的，这是必不可少的。数据。请注意，设备优化有几个方面，例如膜厚度和成分。
