Research Interests

 

Claire Berger is Director of Research at the French National Center for Scientific Research - Néel Institute working at the Georgia Institute of Technology in W. A. de Heer’s group. She obtained the PhD in Physics from the University of Grenoble, France, with a dissertation on the electronic properties of AlMn quasicrystals. She then moved to a postdoc position at the Centre d’Etudes Atomiques, where she produced and studied amorphous films, and was hired as a researcher at the CNRS ‘s Laboratory for Study of Electronic Properties of Solids (LEPES), in Grenoble. She focused the first part of her carrier on electronic properties of quasicrystalline materials grown and characterized at LEPES. She contributed to the experimental evidence for a metal-insulator transition in these metal- based compounds.

 At Georgia Tech, her current scientific interests are primarily nanoscience and electronic property of graphene-based systems. She co-authored the first article demonstrating the two dimensional properties of graphene and proposing graphene for electronics, and together with Walt de Heer and Phil First she co-authored the first patent for graphene electronics (2003).

 She is co-author of more than 200 publications in international journals, has a citation index of 10,880 and an H index of 41.
