Carbon-based nanostractures as terahertz emitters and detectors

We propose and justify several schemes utilizing the unique electronic properties of different types of carbon nanotubes for a broad range of applications to terahertz (THz) optoelectronics, including THz generation by hot electrons in quasi-metallic nanotubes, frequency multiplication in chiral-nanotube-based superlattices controlled by a transverse electric field, and tunable THz radiation detection and optically-pumped emission in armchair nanotubes in a strong magnetic field.
