Abstract

Organic electrochemical transistors (OECTs) with two topologies and three ionic liquid electrolytes were analyzed to get information about their influence on the selected transistor’s characteristics. The channel of the OECT device was based on conductive polymer poly(3,4-ethylenedioxy-thiophene) poly(styrene sulfonate) (PEDOT:PSS). Dynamic characteristics were measured and analyzed. From the results follow that in the case of the double GATE configuration both the rise and decay current components contain diffusion contribution which limits the use of OECT in switching applications. Besides the influence of the OECT topology, the used electrolytes significantly affect transistors characteristics. Ionic liquid 1-butyl-3-methylimidazolium trifluoromethane-sulfonate (BMIM OTf) exhibited the best performance among the other tested ILs based on methylimidazolium.
