Claire Berger

Claire Berger (* 1960 ) is a French solid-state physicist.

Berger received his doctorate in 1987 from the University of Grenoble with a dissertation on the electronic properties of aluminum-manganese quasicrystals . As a post-doctoral student , she studied amorphous films at the Center D'Etudes Atomiques and then did research for the CNRS at their laboratory for electronic properties of solids (LEPES) in Grenoble. There she was involved in the detection of a metal-insulator transition in a quasicrystal. She is Research Director at CNRS and Professor at the Georgia Institute of Technology , where she works with Walter de Heer in the field of graphene electronics.

With Walter de Heer and Phillip First and others, she is co-author of a pioneering paper on graphenes and their use in electronics. In 2006 her, de Heer and First were also granted the first patent for graphene electronics. She is one of the highly cited scientists with over 200 publications as an author or co-author.

She is a Fellow of the American Physical Society , received the Ancel Prize from the French Physical Society and the CNRS Medal for Young Scientists.
