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

Autor: Magnus Berggren, Ari Laiho, Oscar Larsson, Xavier Crispin, Wolfgang Schmickler

Publikováno v: Advanced Materials

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 elec
