Selection of Carbon NanoTubes
Schematic for the selective blowing of metallic nanotubes. (A) A selection
of both metallic and semiconducting nanotubes are deposited across
the channel between two electrodes. (B) When a voltage is applied
between the two electrodes the metallic tubes carry a large current
and thus blow up, leaving behind the semiconducting tubes.

Each drop in current corresponds to 10 uA, which is the expected maximum
current density for a carbon nanotube.
