Butt, H and Dai, Q and Ranjith, R and Wilkinson, TD and Amaratunga, GAJ (2011) Plasmonic band gaps and waveguide effects in carbon nanotube arrays based metamaterials. ACS Nano, 5. pp. 9138-9143.Full text not available from this repository.
Highly dense periodic arrays of multiwalled carbon nanotubes behave like low-density plasma of very heavy charged particles, acting as metamaterials. These arrays with nanoscale lattice constants can be designed to display extended plasmonic band gaps within the optical regime, encompassing the crucial optical windows (850 and 1550 nm) simultaneously. We demonstrate an interesting metamaterial waveguide effect displayed by these nanotube arrays containing line defects. The nanotube arrays with lattice constants of 400 nm and radius of 50 nm were studied. Reflection experiments conducted on the nanoscale structures were in agreement with numerical calculations.
