Abstract

We fabricated field-effect transistors of isolated single-walled carbon nanotubes (SWNTs) that were debundled by density gradient ultracentrifugation (DGU). A solution of SWNTs in heavy water was mixed with iodixanol and then centrifuged. After DGU, the layer in which the SWNTs with a chirality of (6,5) were enriched was extracted and diluted with ultrapure water. The debundled SWNTs were bridged by dielectrophoresis between pairs of Pd electrodes. We also characterized the electrical properties of the SWNTs. Some SWNTs showed semiconductor characteristics, whereas others showed metallic behavior.
