Title: Macroscale Single Crystal Graphene: Basic Science of Tensile Loading Mechanics and Broader Impact
The macroscale tensile loading mechanics of monolayer single crystal graphene (SCG) is presented. We have measured the Young’s modulus, strain at failure, and tensile strength, as a function of crystallographic orientation. SCG is grown on either single crystal Cu(111) or on single crystal Ni(111) foils, and ‘dog bone’ samples with gauge length of 10 mm and width 2 mm are found to have remarkably high tensile strength values, which we suggest bodes well for applications, particularly for ‘lightweighting’ in space and aerospace, among others. An earlier version of this study (in progress) has been archived, please see [1]. Supported by the Institute for Basic Science (IBS-R019D1).
Dr. Ruoff UNIST Distinguished Professor (The Departments of Chemistry and Materials Science, and The School of Energy Science and Chemical Engineering), directs the Center for Multidimensional Carbon Materials (CMCM), an Institute for Basic Science Center (IBS Center) located at the Ulsan National Institute of Science and Technology (UNIST) campus. Prior to joining UNIST in 2014, 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 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, and did research at the Molecular Physical Laboratory, SRI International for 6 years after being a postdoctoral fellow at IBM TJ Watson Research Center.

The IBS Center for Multidimensional Carbon Materials (CMCM) supports a talented international team of highly collaborative researchers that design, synthesize and study new forms of carbon and related materials, many of which are expected to have exceptional physical and electronic properties. The center is located in a new building at the Ulsan National Institute of Science and Technology (UNIST), nestled in a beautiful area near the port cities of Ulsan and Busan. Ulsan is famous for its shipbuilding, automobile manufacturing, and petrochemical and chemical industries, and thus an ideal location to interface science with industry. Members and visitors of the CMCM will enjoy an intellectually stimulating environment that fosters dynamic exchange within the center and abroad through its extensive, international network of research institutions and programs.
