摘要
距离发现反铁电已有70多年的历史,其独特的电场诱导相变行为使其在储能、换能器、驱动器、电卡制冷、负电容晶体管、热管理等领域显示出了巨大的应用价值.随着薄膜生长技术的发展及器件小型化、集成化趋势的需求,反铁电薄膜受到越来越多的关注.大量研究表明,反铁电从块体到薄膜显现出与块体不同的新奇物性,同时也面临更多挑战,如尺寸效应使得其反铁电特性在临界厚度下减弱甚至消失等.在此基础上,回顾了锆酸铅基反铁电研究的发展历史,从反铁电的起源、结构、相变到应用等方面进行了讨论.希望能够吸引更多的研究者关注反铁电薄膜的发展,探索未知的奥秘,共同开发更多的新材料和新应用.
It has been more than 70 years since the first anti-ferroelectric was discovered.Its unique electric-fieldinduced phase transition behavior shows great potential applications in the fields of energy storage,electrocaloric,negative capacitance,thermal switching,etc.With the development of advanced synthesis technology and the trend of miniaturization and integration of devices,high-quality functional oxide films have received more and more attention.A large number of studies have shown that anti-ferroelectric thin film exhibits more novel properties than bulk,but it also faces more challenges,such as the disappearance of antiferroelectricity under a critical thickness induced by size effect.In this paper,we review the development history of lead zirconate-based anti-ferroelectric thin films,and discuss their structures,phase transitions and applications.We hope that this paper can attract more researchers to pay attention to the development of antiferroelectric thin films,so as to develop more new materials and explore new applications.
