主要研究方向:

多维度多模式成像方法发展与材料物理

1. 结合深度学习技术以及4D-STEM等新型电子显微探测方法，发展高通量、高精度的多维度原子成像方法；

2. 结合STM+TEM研究手段，发展适用于量子材料的多模式、跨平台的研究方法；

3. 针对功能材料、非晶态物质、量子材料等关键科学问题进行研究。

过去的主要工作及获得的成果:

近些年在成像方法多个前沿领域（原位STM+TEM表征技术、三维原子成像算法、计算成像定量化分析等）进行了深入的研究与拓展。发展了原位STM+TEM表征技术，将STM扫描探针引入TEM中；应用原位电镜技术对电阻存储器机理、固液界面的纳米颗粒与生物大分子的动力学等科学问题进行了探讨，揭示了忆阻器的双极性电化学传质机制、固液界面纳米颗粒的RLA团聚效应等重要科学现象，研究成果得到国际同行的高度评价。近年来，发展了扫描式三维原子断层成像技术，将三维原子成像技术拓展到层状材料与薄膜材料中，在国际范围内将原子的三维定位精度推至4皮米。将此方法成功应用于二维半导体材料，澄清了掺杂、PN结界面等对能带调控的微观物理机制，在原子尺度揭示了掺杂原子和PN结界面导致的晶格结构局域畸变与离域效应以及对电子声子结构的影响。
