Impression of graphene by Jannik Meyer

Within the next 10-15 years, say, Moore's Law will cease to hold for chips made from silicon, because individual transistors will get so small that silicon ceases to function as a semiconductor. Science Daily reports on work published on 17 April 2008 in the peer-reviewed journal Science - abstract - by Ponomarenko, Schedin, Katsnelson, Yang, Hill, Novoselov, and Geim , a team based mainly at the University of Manchester's Centre for Mesoscience and Nanotechnology that proves that transistors one atom thick and 10 atoms wide can be made using graphene, a hexagonal mesh of carbon atoms that is one atom thick. 

For more on graphene, see the frequently updated Wikipedia article, and this 10 April 2007 Scientific American article by JR Minkel, who also comments  in the Scientific American on 18 April 2008 about the "smallest transistor" claim.
