Electric-field-induced spectral changes in single-walled carbon nanotubes were studied using a thin-film transistor configuration. As a function of electric field, the optical spectra displayed continuous intensity modulations. This is the direct evidence of carrier accumulation, and the amount of accumulated carriers was quantitatively consistent with the carrier density in the nanoscale wire-form field-effect transistor model.
