摘要：

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 width and channel length were also significantly decreased by increasing ink viscosity. Source and drain electrodes with both width and channel length of less than 50 mu m and near-perfect film uniformity were printed and integrated with poly(3,3(')-didodecylquarter-thiophene) semiconductor as high-performance transistors.
