Scientists scale terahertz peaks in nanotubes


Rice U. researchers find plasmonic root of terahertz signals in some carbon nanotubes

Carbon nanotubes carry plasmonic signals in the terahertz range of the electromagnetic spectrum, but only if they’re metallic by nature or doped.

In new research, the Rice University laboratory of physicist Junichiro Kono disproved previous theories that dominant terahertz response comes from narrow-gap semiconducting nanotubes.
