The diverse electronic, mechanical, and combined electromechanical properties of carbon nanotubes together with the ability to gate or control the conductivity along the length of the tube make them attractive candidates for application in integrated molecular electronics. Tombler et al. show that the conductivity in an individual semiconducting nanotube can be controlled locally with the biased tip of a scanning probe microscope. As the probe is brought into close proximity to the tube, the bias locally modifies the band profile in the tube allowing it to be switched between a conducting and non-conducting state. Moreover, the technique can be used to determine the electronic properties of individual tubes that make junctions.ISO
