a Hall voltages and the applied magnetic field B in the out-of-plane direction and (b) Hall carrier density nH derived from the inverse Hall coefficient \({n}_{{\rm{H}}}={(e{R}_{{\rm{H}}})}^{-1}\) and Hall mobility μH estimated from μH = RHσ for PBTTT thin films doped with F4TCNQ (blue), Mo(tfd-COCF3)3 (green), anion-exchange (orange), and TBPA-TFSI (red) at 240 K. The error bars in nH and μH represent uncertainties in extracting the Hall voltage from the fitting and the thickness of the polymer thin films and represent one standard deviation. c Out-of-plane XRD measurements of a PBTTT film with a thickness of 5 μm before and after TBPA-TFSI doping. d Miller index dependence of FWHM for pristine and TBPA-TFSI doped PBTTT thick film.
