AB  - Piperidine is found to be an efficient electron doping agent that converts 
      as-prepared p-type single-walled carbon nanotube (SWCNT) field effect transistors 
      (FETs) into n-type SWCNT-FETs. Electron transfer from the amine group in 
      piperidine to the SWCNTs is suggested to be the origin of the p- to n-type 
      conversion. The effect of electron doping is further supported by the Raman 
      tangential G(+) and G(-)-peak downshift up to 3 cm(-1) without the peak 
      broadening. No detectable change in the Raman D-peak suggests non-covalent 
      attachment of piperidine to the SWCNTs. A low temperature (110  degrees C) Si(3)N(4) 
      passivation layer is used to maintain the long term air stability of the 
      converted n-type devices. A complementary SWCNT inverter is demonstrated through 
      integrating the n- and p-type SWCNT-FETs.
