Abstract

We show that self-assembled films of horizontally aligned carbon nanotubes are a electrostatically tunable hyperbolic metamaterial using spectroscopic ellipsometry. We map the hyperbolic dispersion of plasmonic modes in aligned carbon nanotube films using transmission measurements of nanoribbon resonators and find good agreement with a theoretical model based on the optical properties dervied from the ellipsometry. Self-assembled films of carbon nanotubes are well-suited for applications in thermal emission and photodetection, and they serve as model systems for studying light–matter interactions in the deep subwavelength regime.
