The biggest challenge in making a single-molecule device is achieving electrical contact between individual molecules. Now new techniques that vaporize carbon to form nanotubes, and deposit material onto silicon oxide substrates, have made it possible to improve the electrical contact. The Delft team made a three-terminal device consisting of the nanotube and two metal electrodes. Electrical measurements on the nanotube shows that it can be described by the semiclassical band-bending models that are used for traditional semiconductor devices. Fabrication of the device - which the team call a single carbon nanotube field-effect transistor or TUBEFET - is described as "relatively straightforward".
