FIG. 1.

(Color online) Theoretical room temperature conductance of a single-walled carbon nanotube. For each tube, 2 and diameters, the total conductance is when three subbands are considered. Also shown is the case when only one subband is considered ( here). Results also give the mean free path in microns multiplied by the number of included subbands .

FIG. 3.

(Color online) Simulations of the theoretical peak conductance for a length single-walled carbon nanotube as a function of diameter at . Results also indicate the on state mean free path and the on resistance of the nanotube (excluding contacts).

FIG. 4.

Comparison of theoretical and experimental (Ref. 5) peak field-effect mobilities and on resistances vs temperature. A single-walled nanotube of length and a diameter of is considered. The on resistance is , where is (Ref. 5).
