Abstract

We have studied the optical and electrical performance of nitrogen-doped single-walled carbon nanotube films, measured in terms of optical transmittance and sheet resistance. Using a simple resistor network model to study the geometric scaling of the optical transmittance to sheet resistance ratio, and data from similar undoped films, we show that the nitrogen-doped films have a significantly increased sheet resistance. The analysis shows that this effect is likely due to an increase in the intrabundle resistances. A possible cause is the increased backscattering of charge carriers by defect sites in the nanotubes.
