  The diverse applications of terahertz radiation and its importance to
fundamental science makes finding ways to generate, manipulate, and detect
terahertz radiation one of the key areas of modern applied physics. One
approach is to utilize carbon nanomaterials, in particular, single-wall carbon
nanotubes and graphene. Their novel optical and electronic properties offer
much promise to the field of terahertz science and technology. This article
describes the past, current, and future of the terahertz science and technology
of carbon nanotubes and graphene. We will review fundamental studies such as
terahertz dynamic conductivity, terahertz nonlinearities, and ultrafast carrier
dynamics as well as terahertz applications such as terahertz sources,
detectors, modulators, antennas, and polarizers.
