Testing the Conductivity of Carbon Nanotubes (image) Rice University Share Print E-Mail Caption Scientists at Rice and Swansea universities used tungsten probes attached to a scanning tunneling microscope to test the conductivity of carbon nanotubes before and after treatment to decontaminate them. The sequence above shows one probe at the end and the other moving along the length of an isolated nanotube.
