Scientists in the U.S. and China have adopted a vertical framework to produce high-performance organic electrochemical transistors (OECTs
Stacking OECTs like sandwiches supports switching speeds that exceed 1 kilohertz, stability across more than 50,000 cycles, less than 100-nanometer-long channel lengths, and transconductances of 200 to 400 millisiemens.
The researchers sandwiched the channel between a bottom source electrode and a top drain electrode; the channel consists of a semiconducting ion-permeable compound combined with a polymer that adds robustness and stability, while an electrolyte lies atop the channel and drain electrodes.
The researchers said they could manufacture these transistors in a simple, scalable manner using standard fabrication methods.
