Visualized atomic scale manufacturing

【Abstract】

A fundamental understanding of atomic-scale manufacturing requires the ability to capture real-time structural evolution under complex processing conditions involving diverse external fields and environments. By setting up an nano-laboratory inside a transmission electron microscope (TEM), we have developed in situ TEM-based techniques that enable simultaneous fabrication and observation at the atomic scale, making manufacturing to become visible, understandable and controllable. Using these methodologies, the studies directly reveal new phenomena and underlying mechanisms in various manufacturing processes, including electron-beam-assisted and electrically/thermally-driven fabrication. These results provide a foundation for atomic-precision processing and the on-demand construction of materials and structures, thereby opening new opportunities for the development of advanced fabrication strategies, novel materials, and next-generation devices. 

要从根本上理解原子尺度制造，就必须能够捕捉在涉及多种外场和环境的复杂加工条件下，材料结构的实时演化过程。通过在透射电子显微镜（TEM）内部搭建纳米实验室，我们开发出了基于原位透射电子显微镜的技术。该技术能够在原子尺度下同时实现制造与观测，进而让制造过程变得 “可见、可懂、可控”。借助这些方法，相关研究直接揭示了多种制造工艺中的新现象及内在机制，其中包括电子束辅助制造、电驱动制造和热驱动制造等。这些研究成果为原子精度加工以及按需构建材料与结构奠定了基础，从而为先进制造策略、新型材料和下一代器件的发展开辟了新机遇。
