Abstract

Time-domain spectroscopic studies provide a unique perspective on the materials properties and the microscopic processes underlying them in carbon nanotubes. Ultrafast spectroscopy is used to study the dynamics and kinetics of scattering and relaxation processes from the femtosecond (1 fs equivalent to 10(-15) s) to the picosecond timescale. This provides crucial information on carrier and exciton dynamics that underpin a variety of potential applications of carbon nanotubes, from their use as current-carrying quantum wires, through light-emitting or detecting nanodevices, to their use in light-harvesting technologies and photovoltaics. Background information on the ultrafast spectroscopic techniques of greatest applicability to nanotubes is also provided.
