Description:
Electron energy-loss spectroscopy (EELS) is widely used to identify elemental compositions of materials studied by microscopy. We demonstrate that the sensitivity and spatial resolution of EELS can be extended to the single-atom limit. A chemical map for gadolinium (Gd) clearly reveals the distribution of Gd atoms inside a single chain of metallofullerene molecules (Gd@C82) generated within a single-wall carbon nanotube. This characterization technique thus provides the "eyes" to see and identify individual atoms in nanostructures. It is likely to find broad application in nanoscale science and technology research.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suenaga, K -- Tence, M -- Mory, C -- Colliex, C -- Kato, H -- Okazaki, T -- Shinohara, H -- Hirahara, K -- Bandow, S -- Iijima, S -- New York, N.Y. -- Science. 2000 Dec 22;290(5500):2280-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de Physique des Solides (CNRS UMR 8502),Universite Paris-Sud, Orsay 91405, France. suenaga@meijo-u.ac.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11125135" target="_blank"〉PubMed〈/a〉
