The organic field effect transistor has a layered construction. A voltage applied to the gate causes the polymer layer to become a semiconductor and allows current flow between the source and drain contact.


All parts of an OFET can be made from plastics or thin flexible metals so that this could be used for flexible or printed electronics.
