Figure 6.

Map of the D/G+ peak intensity ratio of the FET. The green color around the two electrodes sketched by dashed lines represents values of 0.31 ± 0.02. In red and dark color, the intensity ratio is not defined due to the absence of Raman signal in those regions. No particular increase in defect concentration is observed at the CNT/electrode interface.
