Graphene grown epitaxially on silicon carbide (epigraphene) presents the textbook properties of graphene, and can be grown reproducibly and reliably at a very large scale, all the while realizing high quality graphene structures at the nanoscale. Depending on the interaction with the growth substrate, epigraphene sh<\/span><\/p>\n<p><span style=\"font-family: Calibri, sans-serif; font-size: 11pt;\">ows a range of properties from semiconducting behavior to exceptional conduction. Narrow ribbons grown on facets etched in the SiC substrate show room temperature single channel quantized ballistic conductors on distances greater than 15 \u00b5m. Charge neutral, epigraphene grown on these facets gives access to physics at the Dirac-point. Besides their importance for fundamental science, epigraphene nanoribbons are readily produced by the thousands and their room temperature ballistic transport properties are promising for advanced nanoelectronics.<\/span><\/p>\n<p><strong>Biography:<br \/>\n<\/strong><\/p>\n<ul>\n<li>Director of Research at Centre National de la Recherche Scientifique, France<\/li>\n<li>Professor of the Practice, Georgia Institute of Technology, Atlanta<br \/>\nemail: cberger@georgiatech-metz.fr claire.berger@physics.gatech.edu<\/li>\n<\/ul>\n<p><strong>Education<\/strong><\/p>\n<ul>\n<li>University Joseph Fourier, Grenoble - France, PhD, Physics, 1987.<\/li>\n<li>University Joseph Fourier, Grenoble - France, Habilitation \u00e0 Diriger des Recherches, 1996.<\/li>\n<\/ul>\n<p><strong>Appointments and Research Activities<\/strong><\/p>\n<p><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/01\/graph2.gif\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-38864\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/01\/graph2.gif\" alt=\"\" width=\"144\" height=\"129\" \/><\/a>1988-2001: CNRS Research Fellow (Grenoble):<br \/>\n<em>Transport properties of quasicrystalline and related materials, Quasicrystal growth and structural studies, Metal-insulator transition, quantum interference effects<\/em><\/p>\n<p>2001-present: CNRS - Georgia Institute of Technology dual appointment.<\/p>\n<p>2007: CNRS Research Director (Institut N\u00e9el, Grenoble)<\/p>\n<p>2017: CNRS-Directeur de Recherches 1\u00e8re classe and GT Professor of the Practice<br \/>\n<em>Growth, electronic and structural properties of low dimensional graphite, epitaxial graphene, carbon nanotubes.
