AB  - We demonstrate lithographically fabricated Si nanowire field effect transistors 
      (FETs) with long Si nanowires of tiny cross sectional size ( approximately 3-5 nm) exhibiting 
      high performance without employing complementarily doped junctions or high 
      channel doping. These nanowire FETs show high peak hole mobility (as high as over 
      1200 cm(2)/(V s)), current density, and drive current as well as low drain 
      leakage current and high on/off ratio. Comparison of nanowire FETs with nanobelt 
      FETs shows enhanced performance is a result of significant quantum confinement in 
      these 3-5 nm wires. This study suggests simple (no additional doping) FETs using 
      tiny top-down nanowires can deliver high performance for potential impact on both 
      CMOS scaling and emerging applications such as biosensing.
