In this study, PEDOT thin films polymerized with Iron(III)tosylate (Fe(PTS)3) and grown on atomically smooth and highly dense 3-aminopropyltriethoxysilane self-assembled monolayer (APS-SAM) surfaces by VPP method have been investigated. PEDOT thin films were synthesized on APS self-assembled SiO2 wafer surface at two different concentrations (20 wt% and 40 wt%) and growth time (3 and 30 minutes), and then their sheet resistance were measured and compared. PEDOT thin films grown with 20 wt% Fe(PTS)3 oxidant are highly conductive when compared with the film grown with 40 wt% Fe(PTS)3, as ascertained by the measured sheet resistance values down to 0.06 Ω/cm. It clearly suggests that 20 wt% is more effective oxidant concentration for VPP than 40 wt% even though the film grown with 40 wt% oxidant has better quality than the film with 20 wt% Fe(PTS)3 does.
