OECT Device Physics
Organic electrochemical transistors (OECTs) are thin-film transistors with an organic semiconductor channel between source and drain electrodes. OECTs are structured much like organic field-effect transistors (OFETs) with the distinction that OECTs have an electrolyte layer between the channel and the gate electrode instead of a standard dielectric. We develop and validate models that provide quantitative explanations for previously unexplained characteristics. Ultimately, these models inform the design of OECT sensors and circuits, and they provide a way to measure the material properties of the polymer semiconductors used in OECTs, thus aiding the development of new polymers for performance optimization in different applications.
