On chips where components are 22 nanometres in size, transistor gates are about 42 atoms across. "Now we have just demonstrated the world's first electronic device in silicon systematically created on the scale of individual atoms," said Professor Michelle Simmons, lead researcher on the project at the University of New South Wales.If an entire chip could be made with every one of its billions of transistors made from the silicon crystals, it could mean an "exponential" leap in processing power, said Professor Simmons.</blockquote>
