| Research Abstract |
DNA-wrapped single-wall carbon nanotubes (SWNTs) and double-wall carbon nanotubes (DWNTs) have been synthesized and are length-separated by high-performance liquid chromatography (HPLC) with a specially designed HPLC column. Furthermore, we have found that DNA-wrapped SWNTs provides an effective, scalable way to fabricate the super-uniform networks of highly isolated, structure-sorted SWNTs for thin-film transistors (TFTs). The DNA-SWNTs are easily formed into uniform, desired-density networks of individual nanotubes. By tuning the nanotube density, the TFTs with an on/off ratio of 10^3-10^5 can easily be achieved even without the removal of metallic SWNTs.
