Abstract:
1. An organic field effect transistor, comprising: a substrate; a gate electrode, a source electrode and a drain electrode, at least one of said electrodes disposed on the substrate; a dielectric layer in contact with the gate electrode; an organic semiconducting layer in contact with the dielectric layer; the source electrode and the drain electrode in contact with the organic semiconducting layer; a first interface region situated between the gate electrode and the dielectric layer; a second interface region situated between the dielectric layer and the organic semiconducting layer; a third interface region situated between the organic semiconducting layer and the source or drain electrodes; and a bifunctional contact-enhancing agent situated in at least one of said interface regions so as to form a chemical or physical bond between adjacent said layers or said electrodes, said bifunctional contact-enhancing agent comprising one or more materials selected from the group consisting of:
