Challenge to Seeing Atomic Structures of Nano-materials with Electron Microscopy

Challenge to Seeing Atomic Structures of Nano-materials with Electron MicroscopyProfessor Sumio Iijima
Meijo University
Nagoya, Japan Abstract
Nanoscience deals with nano-scale structures of materials and therefore controlling the structures is crucial. A typical example of nanostructures is carbon nanotubes and their many unique properties have been investigated theoretically and experimentally, and brought a new concept of materials into condensed matter physics. More importantly, nanoscience is closely related to nanotechnology and thus to industrial applications as we see in many fields of carbon nanotube research. An important issue for nanoscience is characterization of materials. In the case of carbon nanotubes their exact atomic structures are determined by means of electron microscopy, Raman and photoluminescence spectroscopy, etc., where sometimes commercially available instruments are not sufficient and need substantial modification for each particular purpose, where “do it yourselfâ€Â becomes important. We demonstrate some latest results on structural characterization of carbon nanotubes, graphene, and boron nitride thin films, including “monatomic carbon strings that have been successfully observed in our laboratory. BiographySumio Iijima is a Professor at Meijo University, a Director of the Nano-tube Research Center at AIST and a Senior Research Fellow at NEC, in Japan. After graduating from Tohoku University, he joined Arizona State University where he developed high-resolution transmission electron microscopy (HRTEM) (1970-1982). In 1982 he returned to Japan and joined the NEC Research Laboratories in 1987. In 1991 he discovered carbon nanotubes that have initiated nano-material science and nanotechnology. Professor Iijima has received numerous honors and awards from Italy, Japan, Spain and Switzerland. He is a foreign associate of the National Academy of Science (USA).Time and Location
