Graphene Is a Tunable Plasmonic Medium


June 20, 2012

an infrared laser beam launches plasmons With a beam of infrared light, scientists have sent ripples of electrons along the surface of graphene and demonstrated that they can control the length and height of these oscillations, called plasmons, using a simple electrical circuit. This is the first time anyone has observed plasmons on graphene, sheets of carbon just 1 atom thick, and an important step toward using plasmons to process and transmit information in spaces too tight to use light.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
