Schematic of a SC-SWNT thin film on interdigitated electrodes, together with a SEM image of a representative film.

Conductivity of SWNT films as a function of the duration of metal deposition of Li, Cr, and Au.

FIG. 3.

(a) Cr atoms form bis-hexahapto complexes at the SWNT sidewalls, thereby bridging adjacent carbon nanotubes and reducing the inter-nanotube junction resistance. (b) Electron transfer processes (doping): Li atoms donate electrons to the conduction bands of the SWNTs, increasing conductivity of semiconducting SWNT film by a factor of 100.

FIG. 4.

(a) Conductivity of SWNT films as a function of the duration of metal deposition of Ti, V, Cr, Mn, and Fe. (b) Effect of metal atom deposition on the conductivity of SWNT films. (c) Orbital interaction diagram for (η6-C6H6)2Cr. Adapted from Ref. 18.
