Abstract

With the continuous improvement of in situ techniques inside transmission electron microscope (TEM), the capabilities of TEM extend beyond structurual characterization to high-precision nanofabrication and property measurement, which not only enriches the experimental methods of nanoresearch, but also provides new opportunities for the development in nanoscience and nanotechnology. Based on the idea of "setting up a nanolab inside a TEM", we present our recent progress in carbon related nanomaterials including in situ growth, nanofabrication with atomic resolution, in situ property characterization, nanodevice construction and other possible applications (e.g. a 5nm-diameter hole on graphene for third-generation gene sequencing, the spongy graphene as an ultra-efficient sorbent for oils and organic solvents, etc.).

Speaker's Bio

Prof. Litao Sun currently serves as vice dean of School of Electronic Science and Engineering, Southeast University (SEU), the director of SEU-FEI Nano-Pico Center, and founding chairman of IEEE Nanotechnology Council Nanjing Chapter. He received his PhD from the Shanghai Institute of Applied Physics, Chinese Academy of Sciences in 2005. He worked as a research fellow at University of Mainz, Germany from 2005 to 2008, and a visiting professor at University of Strasbourg, France from 2009 to 2010. Since 2008, he joined SEU and honored as a Distinguished Professor. His research currently focus on controlled synthesis and characterization of carbon-related nanomaterials, in-situ experimentation in the electron microscope, and fundamental understanding and applications of nanostructures in micro/nano systems. He is the author and co-author of over 70 papers and review articles on international journals including Science, Nature Nanotechnology, Phys. Rev. Lett., etc.
