Abstract

Atomic-scale precision manufacturing is fundamental to the construction of next-generation functional devices for information and energy applications. A deep understanding of the nucleation, growth, and structural evolution of nanocrystals under reaction conditions is key to achieving atomic-level precision control. Addressing this scientific challenge, this talk introduces the development of in-situ, dynamic, high-spatiotemporal-resolution characterization methods using an environmental aberration-corrected transmission electron microscope (ETEM). These methods reveal the laws governing structural evolution of nanomaterials under realistic reaction environments.
