We explore the electric-field effect of carbon nanotubes (NTs) in electrolytes. Due to the large gate capacitance, Fermi energy (EF) shifts of order ±1 V can be induced, enabling to tune NTs from p to n-type. Consequently, large resistance changes are measured. At zero gate voltage, the NTs are hole-doped in air with |EF|[approximate]0.3–0.5 eV, corresponding to a doping level of [approximate]1013 cm–2. Hole-doping increases in the electrolyte. ©2001 American Institute of Physics.

  11. This is justified, because kBT is of order of the subband separation at room temperature and because of the relatively short electron-mean free path l<~2pir measured in MWNTs.
