Title：In Situ Research on Experimental Process at Atomic Scale

Abstract：

Based on the idea of "building nanoscale laboratories in transmission electron microscopy", we can use in-plane aberration correction transmission electron microscopy and self-built in-situ operation and performance characterization platforms to achieve in-situ growth materials. Four aspects of our research team in recent years are presented here, including nano-processing, structural performance synchronization, device site construction of, the leading cutting-edge research work. The ultra - efficient adsorption performance of graphene porous structure is reported for the first time. The solid metal nanoparticles were found to have a liquid behavior below 10 nm. A method of in situ construction of electronically driven heterostructures was developed. At the same time, on the basis of field experiment, the possible application of new materials is discussed.
