Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

Advanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a
