23_41/2011Organic Electronics: Controlling the Dimensionality of Charge Transport in an Organic Electrochemical Transistor by Capacitive Coupling (Adv. Mater. 41/2011)

The dimensionality of charge transport (2D versus 3D) in an organic electrochemical transistor depends on the degree of advancement of the electrochemical half-reaction in the organic semi-conductor, which is here governed only by capaci-tive coupling. As reported by Xavier Crispin and co-workers on page 4764, such a transistor with a carbon nanotube network as the gate electrode leads to a bulk transport in the semiconductor.
