High-Gain Chemically Gated Organic Electrochemical Transistor

Siew Ting Melissa Tan et al.

Summary: Organic electrochemical transistors (OECTs) have shown promising performance as transducers and amplifiers of low potentials due to their exceptional transconductance enabled by the volumetric charging of organic mixed ionic/electronic conductors (OMIECs). However, current approaches that directly conduct chemical reactions within the OECT electrolyte do not fully leverage the OECT's large transconductance, resulting in sub-unity transduction of gate to drain current. This study presents an alternative device architecture that separates chemical transduction and amplification processes to achieve high-gain chemical OECT transducers.
