The newest member of\nthe graphiti c family to join the fullerenes and carbon nanotubes\,\nmany of graphene's unique physical properties can be attributed to\nelectrons behaving like massless particles. I will show how the\noptical properties of graphene ar e described by a fundamental\nconstant of nature\, the fine-structure cons tant\, and how this\nallows us to count atomic layers using only a simple optical\nmicroscope. I will also describe the electronic properties of\ngr aphene\, including its ability to function as a transistor and the\nsensit ivity of its electrical conductance to the environment.\nFuture research d irections and potential applications of graphene\nwill be briefly discusse d.\n DTSTART:20091123T230000Z DTEND:20091124T003000Z LOCATION:Maass Chemistry Building\, CA\, QC\, Montreal\, H3A 0B8\, 801 rue Sherbrooke Ouest SUMMARY:Sigma Xi Lecture URL:/channels/event/sigma-xi-lecture-111977 END:VEVENT END:VCALENDAR
