摘要：

We present recent studies of the electronic structure and optical properties of intercalated single-wall carbon nanotubes using high resolution electron energy-loss spectroscopy (EELS) in transmission and optical absorption spectroscopy. Results on nanotubes intercalated with potassium and iron (III) chloride are presented. Changes in the nanotube electronic structure were monitored in-situ by optical absorption and EELS. The modulation of the filling of van Hove singularities is reflected by the intensity variations of the optical excitations. The intensity of the interband transitions is dramatically affected, demonstrating the possibility of tuning the Fermi level to specific bands upon doping.
