Eva Andrei is an experimental condensed matter physicist recognized for her work on low dimensional electron systems, including two-dimensional electrons on helium, magnetically induced Wigner crystal in semiconductor heterojunctions and vortices in superconductors. She is known particularly for her ground-breaking work on the electronic properties of graphene, a one-atom thick membrane of crystalline carbon with extraordinary electronic properties stemming from charge carriers that behave like ultra-relativistic particles.
Background.Following an undergraduate degree from Tel Aviv University Andrei received her Physics PhD from Rutgers University. In 1987, after post-doctoral work at Bell laboratories, she joined Rutgers as an assistant professor of Physics. She is currently a Board of Governors Chaired professor in the department of Physics and Astronomy at Rutgers University.
Andrei is a fellow of the National Academy of Sciences, of the American Academy of Arts and Sciences, the American Physical Society (APS) and the American Association for the Advancement of Science (AAAS). She is the recipient of the Medal of Physics from CEA, a French government research organization, and of the 2010 Rutgers Board of Trustees Award for Excellence in Research.
Andrei is vice chair of the Condensed Matter and Materials Research Committee for the National Research Council, the Chair-elect for the Physics division of the AAAS, and has served on the executive committee of the APS. She has edited Two Dimensional Electrons on Helium and other Cryogenic Substrates published by Kluwer Academic Press. Andrei is currently an editor for the journal Proceeding of the National Academy of Sciences and serves on the editorial board of Solid State Communications.
Research Interests.Andrei employs magneto-transport, scanning tunneling microscopy and spectroscopy to elucidate the electronic properties of graphene and other 2-dimensional materials, and their response to external perturbations such as magnetic field, charge impurities, boundaries and substrate materials. She and her group demonstrated that by suspending graphene so as to leave it unattached to a substrate it is possible to access the intrinsic properties of the unusual charge carriers. This led to the observation of the fractional quantum Hall effect, providing a direct manifestation of unexpectedly strong electron- electron correlations in this material. In 2009, the journal Science cited these findings in its list of the year’s 10 groundbreaking scientific achievements. Another example is the discovery by Andrei and her group of so-called “Van Hove singularities” in the band structure of stacked graphene layers. They showed that by superposing graphene layers so that their relative crystal orientation is twisted away from equilibrium it is possible to change in a controlled way the band structure, a property which is usually considered to be intrinsic to the chemical composition and crystal structure of a material.
