Scientists build single-molecule transistor gated with individual atoms

An international team of scientists has created a field-effect transistor (FET) with a channel that consists of just a single molecule. The transistor is switched on and off by the arrangement of individual atoms around the channel. This isn't the first single-molecule transistor, though the individual-atom gating is rather novel.
