"New graphene transistor promises life after death of silicon chip (image caption) Single-electron transistors carved entirely in a graphene sheet. The central elements are so-called quantum dots allowing electrons to flow one by one. The dots are connected to wider regions (contact pads by nm-wide constrictions) that work as tunnel barriers. Credit: University of Manchester Researchers have used the world's thinnest material to create the world's smallest transistor – a breakthrough that could spark the development of a new type of super-fast computer chip. Professor Andre Geim and Dr Kostya Novoselov from The School of Physics and Astronomy at The University of Manchester, reveal details of transistors that are only one atom thick and less than 50 atoms wide, in the March issue of Nature Materials. They believe this innovation will allow the rapid miniaturisation of electronics to continue when the current silicon-based technology runs out of steam." <more>
