The effect of purification on room temperature electronic transport properties of single-wall nanotubes (SWNT) was studied by submerging the nanotubes into liquid mercury. The conductance plots of purified SWNTs showed plateaus, indicating weak dependence of the electrical resistance on the length of the tube connecting the electrodes, providing evidence of quasiballistic conduction in SWNTs. The electronic mean free path of the purified SWNTs reached a few microns, which is longer than that of the as-produced SWNTs, and which is consistent with the calculation based on the scattering by acoustic phonons.

    A multi-walled carbon nanotube and dode-canethiol (DDT) modified gold electrode (i.e. MWNTs/DDT/Au) was prepared and characterized. When the gold electrode was modified with a DDT self-assembled monolayer (SAM) followed by a MWNT film, the electrode area increased by a factor of about 4. At the...
