In Situ TEM Characterization and Manipulation of Advanced Nano-devices
Room 5506 (via lift 25/26), Academic Complex, HKUST


Transmission electron microscopy (TEM), with its high spatial resolution and versatile external fields, is undoubtedly a powerful tool for the static characterization and dynamic manipulation of nanomaterials and nanodevices at the atomic scale. The rapid development of thin-film and precision microelectromechanical systems (MEMS) techniques allows 2D layered materials and nanodevices to be probed and engineered inside TEM under external stimuli such as thermal, electrical, mechanical, liquid/gas environmental, optical, and magnetic fields at the nanoscale. Here, taking advantage of advanced in situ transmission electron microscopy, we manipulated interfacial defects in Ⅲ-Ⅴdevices [1, 2] and RRAM [3]. We also observed the whole growth process of the monolayer graphene and MoS2 nanoribbon at real time. The progress of the in situ TEM paves the way to future high-speed and high-reliability devices [4,5].
