Abstract
An organic field effect transistor utilizes a bifunctional contact-enhancing agent at various interfaces to improve carrier mobility through the organic semiconductor layer, to improve carrier injection, and to enhance adhesion via a bifunctional mechanism. The contact-enhancing agent can be situated between the gate electrode () and the dielectric layer () to form a chemical or physical bond between the gate electrode and the dielectric layer. It can also be situated between the dielectric layer and the organic semiconducting layer (), or between the source and drain electrodes () and the organic semiconducting layer.
