  • Abstract
    We report ultrafast mid-infrared studies of individualized semiconducting carbon nanotubes. Transient spectra of (6,5) and (7,5) nanotubes evidence photoinduced absorption around 200 meV, associated with intra-excitonic transitions that reflect quasi-1D exciton correlations and dynamics.
