Rough estimation for contact resistance ( R c ) at the electrode-SWNTs interface. The ΔRii (values reported in Table 1) is the result of Rc, Rintratube, and Rcnt-cnt changes upon annealing. With additional annealing step (case (i)) carried out before electrode deposition, lesser resistance reduction was observed (ΔRi <ΔRii). This resistance change (ΔRi) is deduced to be the Rc contribution from the metal electrode.
