FIG. 1.

(a) Molecular structure of RR-P3HT (head-to-tail). (b) Top view and cross-sectional view of the device structure of FET and electrochemical doping of RR-P3HT film. The electrolyte and the counter electrode were not used for the FET. A part of the film out of the comb-shaped electrodes area was removed for accurate determination of the conductivity and the film area.

Main panel: Transfer characteristics of the RR-P3HT film FET. Arrows show directions of scan. was kept at during measurement. A dashed line and a dotted line represent off-state current and a linear fit for the leftward scan, respectively. Inset: Field-effect mobility vs derived from the plot for leftward scan in (a).
