New concepts for the development of carbon nanotube materials for advanced photonics applications

Like all nanostructures, carbon nanotubes have interesting electromagnetic properties in the near field. The electromagnetic field near the cylindrical nanotube surface is affected by the electronic band structure, surface conductivity, and surface curvature of the nanotube. As a result, the interactions between the surface electromagnetic modes of the nanotube and, say, a surface excitonic state, or an atom (ion, molecule) doped into the nanotube have specific behaviors that have not been deeply explored thus far.
