Inkjet printing narrow electrodes with <50 μm line width and channel length for organic thin-film transistors

We demonstrate a strategy for inkjet printing high resolution silver electrodes from silver precursor composition for organic thin-film transistors. Line width, channel length, and film uniformity of printed electrodes were investigated as functions of dot-to-dot spacing, solvent composition, and ink viscosity. Both line width and film uniformity were greatly improved by simultaneously optimizing dot-to-dot spacing and solvent composition. Line …
