The dimensionality of charge transport in an organic electrochemical transistor depends on the degree of advancement of the electrochemical half‐reaction at the organic semiconductor/electrolyte interface. A carbon nanotube (CNT) nanoporous gate electrode leads to bulk transport in the semiconductor, while a flat Au gate electrode allows for localizing of the electrochemical oxidation of the semiconducting polymer at the organic semiconductor/electrolyte interface.
