Description:
The reduced form of graphene oxide (GO) is an attractive alternative to graphene for producing large-scale flexible conductors and for creating devices that require an electronic gap. We report on a means to tune the topographical and electrical properties of reduced GO (rGO) with nanoscopic resolution by local thermal reduction of GO with a heated atomic force microscope tip. The rGO regions are up to four orders of magnitude more conductive than pristine GO. No sign of tip wear or sample tearing was observed. Variably conductive nanoribbons with dimensions down to 12 nanometers could be produced in oxidized epitaxial graphene films in a single step that is clean, rapid, and reliable.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wei, Zhongqing -- Wang, Debin -- Kim, Suenne -- Kim, Soo-Young -- Hu, Yike -- Yakes, Michael K -- Laracuente, Arnaldo R -- Dai, Zhenting -- Marder, Seth R -- Berger, Claire -- King, William P -- de Heer, Walter A -- Sheehan, Paul E -- Riedo, Elisa -- New York, N.Y. -- Science. 2010 Jun 11;328(5984):1373-6. doi: 10.1126/science.1188119.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Chemistry Division, U.S. Naval Research Laboratory, Code 6177, Washington, DC 20375, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20538944" target="_blank"〉PubMed〈/a〉
