Ground-breaking new data - recording atomic-resolution in-situ movies of growing carbon nanotubes and onion-shaped carbon nano structures in a TEM
Data from a JEOL 300kV TEM, JEM-ARM300F, and a new laser system by IDES, Inc. will be presented by the research team of AIST and Osaka University at M&M 2021.
The research group of Dr. Ryousuke Senga, Electron Microscopy Group, Nanomaterials Research Institute, Advanced Industrial Science and Technology (AIST) and Professor Kazutomo Suenaga, Department of Nanocharacterization for Nanostructures and Functions, Nanoscience and Nanotechnology Center, The Institute of Scientific and Industrial Research (ISIR: SANKEN), Osaka University, succeeded in recording atomic-resolution in-situ movies of growing carbon nanotubes and onion-shaped carbon nano structures in a transmission electron microscope (TEM). The structures were formed by laser irradiation of samples made of carbon films and iron nanoparticles.
This experiment was conducted using a JEOL 300kV Transmission Electron Microscope with a cold field emission gun, JEM-ARM300F, and a new system designed by JEOL subsidiary Integrated Dynamic Electron Solutions, Inc. for precisely focusing lasers onto TEM samples, Luminary Micro. This combination of high-performance imaging instrumentation and reduced sample motion due to precision-controlled rapid localized illumination enables extraordinary spatial resolution for in-situ experiments.
