Moore's law of computer chips alludes to the discovery that the number of transistors that can be placed in a given area doubles every eighteen months or so. Since, the former Intel boss's 1960s prediction the law has held steady and acts a roadmap for how well the industry is doing. However, chips are fast approaching physical barriers that might not be surmounted by conventional semiconductor electronics. Graphene, which won its developers in the UK the 2010 Nobel Prize for Physics might offer a way around those obstacles. Georgia Tech researchers have now reported fabricating an array of 10000 top-gated transistors on a 0.24 square centimeter chip, an achievement believed to be the highest density reported so far in graphene devices.
