    An OECT electrode platform for gas sensor applications

  • Original language description

    An organic electrochemical transistor (OECT) involving a source-drain channel based on poly(3,4-ethylene dioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate [BMIM][BF4] as electrolyte is presented. The basic transistor behaviour was studied by the measurement of the current-voltage characteristics (output and transfer characteristics) and the current-time traces of the drain-source current (IDS). Besides the effects of both drain-source voltage (VDS) and gate-source voltage (VGS) on the level of drain-source current (IDS) flowing through the channel, the effect of the gate electrode material on the transistor behaviour was studied as well. The ionic liquid-gate electrode interface was optimized in order to obtain a swift and reproducible modulation of the drain- source current (IDS) by the gate-source voltage (VGS). Subsequently, the optimized OECT device was exposed to a gaseous analyte (NO2) in order to investigate its detection capability. It was observed that the level of the drain-source current (IDS) can be influenced by the gas concentration that the OECT was exposed to. In other words, drain-source current can be modulated by a gaseous analyte instead of the gate-source voltage (VGS), which brings new applications for such an electronic device.
