Abstract: We report on the synthesis of poly(styrene sulphonate) (PSS) doped with iron ions (PSS:Fe) and its electrical properties in J-Field Effect Transistors (J-FET). PSS:Fe films exhibited enhanced ferroelectric and conductance in comparison with non-doped PSS films, with a conductivity of 4.47 10 -6 S/m. In comparison with traditional ferroelectric polymers, such as poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)], PSS:Fe films had coercive fields three orders of magnitude smaller and remnant polarization six orders of magnitude higher. When operated with a negative gate voltage (VG), the drain current (ID) increased significantly, while positive gate voltages reduced the conductor channel and decreased ID. The proposed in-plane geometry with PSS:Fe monolayer films exhibits suitable ferroeletricity characteristics.
