摘要：

电卡效应是指电介质材料中由于施加或去除电场导致的材料温度变化的现象, 包括正电卡效应和负电卡效应两种类型。电卡效应作为一种高效率、无噪音、环境友好的制冷效应, 在固态制冷特别是集成电路制冷领域显示出广阔的应用前景, 在过去的几十年中吸引了科研人员广泛的研究兴趣。研究表明, 通过结合正负电卡效应, 可以显著提高电卡效应的制冷能力。与正电卡效应不同, 负电卡效应因其独特的物理起源, 调控手段极为有限。本文以负电卡效应为中心, 重点介绍反铁电材料中负电卡效应的最新研究进展, 具体内容包括以下四个部分: 首先, 从电卡效应的研究历史出发, 介绍了电卡效应的制冷原理, 介绍了一个典型的能将正、负电卡效应结合的双制冷循环; 其次, 介绍了基于Maxwell关系的负电卡效应间接测试方法, 以及几种负电卡效应直接测试方法, 并讨论了不同方法的适用条件和优缺点; 再次, 以典型的负电卡效应材料——反铁电材料为例, 着重介绍了负电卡效应的物理起源, 综述了反铁电薄膜和反铁电块体材料中的负电卡效应, 并对其它铁电材料中的负电卡效应做了简要介绍; 最后, 对负电卡效应的研究进行了总结和展望。

Abstract:

The electrocaloric effect refers to the phenomenon of the temperature change of a material caused by the application or removal of an electric field, and includes two types, positive electrocaloric effect and negative electrocaloric effect. As a high-efficiency, noise-free and environment-friendly refrigeration effect, the electrocaloric effect shows promising application in the field of solid-state refrigeration, especially in integrated circuit refrigeration, and has attracted extensive research interests over the past decades. It is reported that the cooling capacity of the electrocaloric effect can be significantly improved by combining the positive and negative electrocaloric effects. However, different from the widely studied positive electrocaloric effect, the research on negative electrocaloric effect is relatively rare due to its complex physical origin. This article focuses on the latest research progress of the negative electrocaloric effect in antiferroelectric materials. The specific content includes the following four parts. Firstly, starting from the research history of the electrocaloric effect, the principle of refrigeration of the electrocaloric effect is introduced, as well as a typical dual refrigeration cycle that can combine positive and negative electrocaloric effect. Secondly, the indirect measurement method of negative electrocaloric effect based on Maxwell relationship, and several direct measurement methods of negative electrocaloric effect, and the suitable applying conditions as well as the advantages and disadvantages of different methods are discussed. Thirdly, taking antiferroelectric which is a typical negative electrocaloric effect materials as an example, the physical origin of negative electrocaloric effect is narrated. Then the recent progress of negative electrocaloric effect in the antiferroelectric film and antiferroelectric bulk materials is reviewed. In addition, the negative electrocaloric effect in some other ferroelectric materials is also briefly introduced. Finally, a summary and prospect of the research on the negative electrocaloric effect are put forward.
