Extended Data Fig. 6

a, b, Changes in conductivity as a function of: initiator dopant (F4TCNQ) concentration (a; red); and additional anion (TFSI) concentration following anion-exchange doping (b; red). The conductivity of an F4TCNQ-doped PBTTT thin film in n-butyl acetate (nBA) is also shown as a reference (a; black). Concentration evidently has a limited effect by comparison with the salt species. The error bars in the conductivity stem from uncertainty in the thickness of PBTTT thin films, and represent one standard deviation.
