title: Sulfidative purification of carbon nanotubes integrated in transistors.
abstract: We demonstrate a simple purification method of carbon nanotubes via sulfidation reaction of carbon, C + 2S --> CS2, to selectively remove carbonaceous impurities from nanotubes. The sulfidative purification of carbon nanotubes integrated in field-effect transistors results in a dramatic improvement of switching characteristics due to removal of carbonaceous impurities.
