AB  - Individual single-walled carbon nanotubes (SWCNTs) were synthesized on the 
      patterned water-soluble catalyst by thermal chemical vapor deposition. The 
      individual SWCNTs were obtained by introducing polyvinylpyrrolidone (PVP) as a 
      dispersant. The number of SWCNTs between two electrodes were approximately 1-2 
      with an average diameter of about 1.7 nm and a yield of forming electrodes of 
      nearly 70%. The PVP played an important role in dispersing catalysts and 
      suppressing the active sites to limit the number of SWCNTs during synthesis, 
      which is a critical condition for fabrication of field effect transistors (FETs). 
      The measured I-V characteristics of the over layer-deposited electrodes revealed 
      a clear gating effect in large portion, in good agreement with Raman observations 
      in several excitation energies. The patterning procedure, catalyst preparation, 
      and growth condition for fabrication of the SWCNT-FET were further discussed.
