Novoselov, K. S.; Geim, A. K.; Morozov, S. V.; Jiang, D.; Zhang, Y.; Dubonos, S. V.; Grigorieva, I. V.; Firsov, A. A. 2004. Electric field effect in atomically thin carbon films. Science, 306, 666-669.
Since that publication, co-authors and 2010 Nobel Prize winners Andre Geim and Konstantin Novoselov have published together at least 63 times (as found through an author search in INSPEC). The "Information for the Public" offered at the Nobel Prize website is wonderfully prepared to help non-physicists understand the significance of graphene's development and utilization:
"Graphene is a form of carbon. As a material it is completely new – not only the thinnest ever but also the strongest. As a conductor of electricity it performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it.
"The list of possible applications for graphene is long. The relentless activity that began following its discovery will eventually most likely bear fruit. No-one can predict what the future might bring, not even this year’s Nobel Laureates."Take a look and enjoy the graphics. The images give a much better idea of graphene's structure!
