AB  - We report on the fabrication and transport properties of single-walled carbon 
      nanotube (SWCNT)/polyurethane (PU) nanocomposite microfiber-based field effect 
      transistors (FETs). UV-assisted direct-writing technology was used, and 
      microfibers consisting of cylindrical micro-rods, having different diameters and 
      various SWCNT loads, were fabricated directly onto SiO(2)/Si substrates in a FET 
      scheme. The room temperature dc electrical conductivities of these microfibers 
      were shown to increase with respect to the SWCNT concentrations in the 
      nanocomposite, and were about ten orders of magnitude higher than that of the 
      pure polyurethane, when the SWCNT load ranged from 0.1 to 2.5 wt% only. Our 
      results show that for SWCNT loads </= 1.5 wt%, all the microfibers behave as a FET 
      with p-type transport. The resulting FET exhibited excellent performance, with an 
      I(on)/I(off) ratio of 10(5) and a maximum on-state current (I(on)) exceeding 70 microA. 
      Correlations between the FET performance, SWCNTs concentration, and the 
      microfiber diameters are also discussed.
