Abstract

We report on SOCl 2 doping of separated single-walled carbon nanotubes (SWCNTs) having different properties (metallic, semiconducting, and mixed). SWCNTs were doped by dropping SOCl 2 on a percolated network which was prepared on a Si substrate and the doping effect was evaluated by measuring electrical characteristics. Pristine semiconducting SWCNTs showed p-type transfer characteristics. After SOCl 2 doping, the conductivity of semiconducting SWCNTs increased about two times and the on/off ratio decreased by a factor of 3. Mixed pristine samples showed slight p-type characteristics and turned to metallic characteristics after doping. The network of metallic SWCNTs did not show any significant change of conductivity before and after doping.
