Abstract

We have focused recently on preparing large area Cu foils with (111) orientation by converting as- received polycrystalline Cu foils. The large area Cu (111) foils have been used to prepare large area Cu/Ni alloy (111) foils, and also foils involving other elements such that the foil surface lattice has a close lattice match to graphene and to hexagonal boron nitride (h-BN). (i) Our use of these foils to enable the growth of large area single crystal single-layer graphene and bilayer graphene will be presented. (ii) A brief update on work on attempting to make diamane from AB stacked bilayer (and trilayer and multilayer) graphene by either fluorination or hydrogenation will be given. (iii) We have recently been making polymers that can be converted to diamond and/or carbon rich sp3-bonded carbon materials, and this will be briefly presented. This work was supported by IBS-R019-D1.

Short speaker’s bio

Rodney S. Ruoff, Distinguished Professor, UNIST Department of Chemistry and the School of Materials Science and Engineering, is director of the Center for Multidimensional Carbon Materials (CMCM), an IBS Center located at the Ulsan National Institute of Science and Technology (UNIST) campus. Prior to joining UNIST he was the Cockrell Family Regents Endowed Chair Professor at the University of Texas at Austin from September, 2007. He earned his Ph.D. in Chemical Physics from the University of Illinois-Urbana in 1988, and he was a Fulbright Fellow in 1988-89 at the Max Planck Institute für Strömungsforschung in Göttingen, Germany. He was at Northwestern University from January 2000 to August 2007, where he was the John Evans Professor of Nanoengineering and director of NU’s Biologically Inspired Materials Institute. He has co-authored over 430 peer-reviewed publications related to chemistry, physics, materials science, mechanics, and biomedical science, and is a Fellow of the Materials Research Society, the American Physical Society, and the American Association for the Advancement of Science. He was awarded the 2014 MRS Turnbull Award.
