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. Andrei holds
fellowships in the American Physical Society (APS) and in
the American Association
for the Advancement of Science (AAAS). She is a member
of the American
Academy of Arts and Sciences and a fellow of the National Academy of Sciences . Andrei holds
the Medal of Physics from CEA, a French government research
organization and she received 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 and the Chair-elect for the
Physics division of the AAAS. She has
edited Two
Dimensional Electrons on Helium and other Cryogenic Substrates published by Kluwer
Academic Press and has
served on
the executive committee of the APS. She is currently
an editor for the journal Proceeding
of the National Academy of Sciences and serves on the
editorial
board of Solid
State Communications. Current research Interests.
Andrei employs magneto-transport,
scanning tunneling microscopy and spectroscopy to elucidate the
electronic
properties of graphene and other 2-dimensional materials, and how they
are
affected by 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
its 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 AAAS 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.
