Luttinger-liquid behaviour in carbon nanotubes

Article Abstract:

The Fermi-liquid theory is used to describe electron transport in conductors. In one-dimensional systems weak Coulomb interactions can result in strong perturbations. The resulting Luttinger liquid has different characteristics from its two and three dimensional counterparts. The measurements of the conductance of bundles of single-walled carbon nanotubes (SWNTs) are presented, in agreement with predictions for tunnelling into a Luttinger liquid.

Carbon-based electronics

Article Abstract:

It has been possible to make a transistor from a carbon nanotube. It was established that the tube can be 'turned on' by applying a negative bias to the substrate, inducing holes on the initially non-conductive tube. The device's resistance can be altered by orders of magnitude, and it functions at room temperature. This research will form the basis for further work on the development of electronic devices based on semiconducting nanotubes.
