Originální abstrakt

This article compares three types of organic electrochemical transistors using different ionic liquids (EMIM-TFSI, BMIM-TFS, HMIM-Cl) that differ in the sizes of their cations and anions. In all cases, PEDOT:PSS was used as the conductive channel between the source and drain electrodes. In addition to the current-voltage characteristics input, output, transfer current and transfer voltage), parameters characterizing charge transport, i.e. electron and hole mobility, distance of the Fermi level from the valence/conduction band, monoenergetic trap concentration and its position (in the bandgap) were determined. The obtained results suggest that BMIM-TFS, with its comparable ion sizes, is the most suitable candidate for the construction of electrochemical transistors.
