| 논문초록 | Parallel-type organic electrochemical transistors (p-OECTs) with aqueous electrolyte gate dielectrics have been widely studied for transducing biological signals into electrical signals. However, aqueous liquid electrolyte-based p-OECTs suffer from poor device stability, low transconductance (gm), and limited applications. In this study, a quasi-solid-state ion gel-gated vertical-type OECT (v-OECT) and NOT logic gate are successfully demonstrated by combining both p-type and n-type v-OECTs for the first time. Indacenodithiophene (IDT) polymers with alkyl (PIDTC16-BT) and oligoethylene glycol (OEG) substituents (PIDTPEG-BT) are studied as a channel material, and an ionic liquid in a crosslinked polymer matrix is adopted as a quasi-solid electrolyte. Notably, the v-OECTs have a significantly larger channel area (50 × 50 µm2) and shorter channel length (≈30 nm), yielding a dramatically increased gm. |
