FALL MEETING
Graphene and other materials highlighted at 2010 Materials Research Society Fall Meeting www.mrs.org/fall2010
T
he 2010 Materials Research Society (MRS) Fall Meeting was held in Boston on November 28–December 3. Meeting Chairs Ana Claudia Arias (Palo Alto Research Center), Robert F. Cook (National Institute of Standards and Technology), Clemens Heske (University of Nevada, Las Vegas), and Shu Yang (University of Pennsylvania) compiled a program of 50 technical symposia, broadly divided into the areas of materials for information processing; materials for infrastructure and mechanical applications; materials processing and device fabrication; materials for energy, biological and environmental applications; and exploration of novel materials and their properties. In addition to reports on research results, which is the mainstay of MRS Meetings overall, the Fall Meeting served as host to many other functions of the Society, including public outreach, professional development, and networking across continents in the mission of building the materials field.

Dave Ginley, the 2010 MRS president, paid tribute to the memory of Rustum Roy (the Pennsylvania State University), one of the founders of MRS and president in 1977, who died last summer. Roy stood for interdisciplinarity, and was an innovative thinker, visionary, and an outstanding materials researcher. Following are some of the research highlights reported at the Meeting. For further details, see the symposium summaries posted on the MRS website at www.mrs.org/bulletinfall2010. In addition, proceedings as well as additional meeting highlights are available at website www.mrs.org/fall2010.
Graphene Graphene is among the carbon-based nanomaterials emerging as leading candidates for the fabrication of a new generation of high-performance nanoelectronic devices. This material, which exhibits extraordinary physical properties, received much attention at the Fall Meeting. One of the two 2010 physics

Nobel laureates, Konstantin S. Novoselov (University of Manchester, UK), as well as 2010 MRS Medalist Walter A. de Heer (Georgia Institute of Technology) presented their seminal work on this material. The material was further discussed in various symposia, including in an invited talk by Phaedon Avouris, (IBM T.J. Watson Research Center) who focused on potential applications of graphene in electronics. Novoselov, who shares the 2010 Nobel Prize in physics with Andre Geim (University of Manchester, UK), reviewed graphene’s properties: that the electrons move over large, submicron distances as if they were free of the environment just a few angstroms away; and that the electrons are governed by the Dirac equation, not the Schrödinger equation, mimicking relativistic particles with no rest mass. Novoselov reviewed applications of graphene, including transistors, quantum dots, variable capacitors, and photovoltaics. Reaction with hydrogen turns the semi-metallic graphene into graphane—an insul
