Extended Data Fig. 9 | Magnetotransport measurements of anion-
exchange-doped PBTTT. a, b, Transverse (Hall) voltage values obtained
from PBTTT thin films that have been anion-exchange-doped with
Li-TFSI (a) a nd EMIM-TFSI (b) at various temperatures. c, Effect of
magnetic field, B, o n the differential sheet conductivity
(Δσ = σ(B) − σ(0)) at various temperatures, with B applied perpendicular
to the substrate plane. See Supplementary Information for details on fitting
of the magnetoconductance data.
