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.
