科研人员介绍，在脉冲激光器、新能源汽车等应用的功率电子器件中，有一类名为"电介质储能电容 器"的元件至关重要，它们以极高的功率快速充放电，并且极其耐用。然而，科学家们一直面临一个难 题：如何让这些电容器在保持强大储能能力的同时，还能经受住从极寒到酷热的极端温度考验，并且易 于大规模生产。 此次研究中，利用"闪速退火"工艺，研究人员可仅用1秒钟，就能在硅晶圆上制备出一种名为锆酸铅的 弛豫反铁电薄膜。据介绍，这项工艺技术可以将材料在高温下的特殊结构"冻结"在室温，形成了尺寸不 到3纳米的纳米微畴。这些微小的结构如同一个精密的迷宫，是诱导弛豫反铁电行为，实现高效率储能 的关键。同时，"闪速退火"还让薄膜的"肌理"更加致密均匀，并有效锁住了容易挥发的铅元素，从根源 上减少了材料缺陷，显著降低了漏电流。 新华社沈阳11月15日电（记者王莹）近日，中国科学院金属研究所沈阳材料科学国家研究中心胡卫进研 究员团队携手合作者，开发出一种热处理升降温速率可达每秒1000摄氏度的"闪速退火"工艺，成功制备 出晶圆级高性能储能薄膜。相关成果于11月15日凌晨发表在《科学进展》期刊上，为下一代高性能储能 电容器件的制造开辟了一条新路径 ...
