Controlling the Dimensionality of Charge Transport in an Organic Electrochemical Transistor by Capacitive Coupling

Oscar Larsson, Ari Laiho, Wolfgang Schmickler, Magnus Berggren, Xavier Crispin, Weinheim (2011)

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.
