Tiny transistors nudge the nanoscale

Physicists in the US have taken a significant step towards nanometre-scale electronics by creating the first transistor made from a single atom. A similar device based on a single divanadium molecule - which consists of two vanadium atoms - has also been built by a second US team. The researchers are optimistic that the transistors will prove to be rich sources of exotic electronic effects, and that their achievements will stimulate research that could lead to the development of practical nanoelectronics systems.
