Carbon nanotubes show superconductivity

In a discovery that could aid the development of molecular-scale electronic devices, researchers in Hong Kong have made tiny carbon nanotubes that exhibit superconductivity–a characteristic associated with the loss of electrical resistance.

Grown in the pores of zeolite crystals, these 0.4-nanometer carbon nanotubes (SWNTs) exhibit superconductivity. Z.K. Tang et al.
