An international team has developed the first single-molecule transistor. Surface scientist Werner Hofer of the University of Liverpool and his colleagues have created a prototype molecular transistor that demonstrates how a single charged atom held on a silicon surface can regulate the conductivity of a nearby molecule. The team, which includes researchers at the National Institute for Nanotechnology of the National Research Council in Canada and the University of Alberta showed that they could control the current through a single molecule while all surrounding atoms remain neutral. The research brings science one step closer to the realm of molecular electronics, which will ultimately revolutionize computing, electronics, and telecommunications.
