Abstract

The authors have demonstrated organic thin film transistors (OTFTs) based on the ink-jet printed electrodes in which a reduced channel length is accomplished by laser ablation. Laser ablation on the dried silver nanoparticle electrode formed by ink-jet printing effectively shortened the channel length down to 5 μm, which is difficult to achieve by ink-jet printing alone. Reducing the channel length using this hybrid technique also allows them to observe the contact resistance effect in the OTFTs, which involves the printed silver nanoparticle electrode of a lower work function with respect to the ionization energy of the organic semiconductor.
