基于先进电磁探针的高精度四维时空探测方法与功能性材料的结构与性能研究。
传统的材料表征手段通常只能进行静态观测，并提供低精度的二维微观信息，难以满足高性能功能材料对超快时间响应和高性能密度的研究要求。如何实现材料结构和性能的多维度、高精度探测，是制约材料科学前沿研究的关键共性问题。随着近些年脉冲激光技术、球差矫正电子显微技术、同步辐射技术的快速发展，高亮度、高相干性的激光、电子、X 射线逐渐被应用于材料研究中，为发展下一代探测手段提供了机遇，有望推动材料新现象在精细四维时空中的探索和重大科学问题的解决。此项研究通过将计算成像学的前沿成果与先进电磁探针相结合，发展高精度、低辐照剂量、轻元素敏感、普适的四维时空探测方法，解决材料科学重要问题，发展高性能功能性材料。研究内容包括：
1. 三维原子分辨电子断层成像与非晶材料三维原子结构表征；
2. X射线、电子相干衍射成像与材料结构表征；
3. 超快光学方法在材料物性测量中的应用。
