description

Ink-jet printing is a desirable manufacturing technique for electronic devices as this mask-less, additive method should allow for integration of different electronic components over large substrate areas at low cost. In order to realize entirely jet-printed devices, appropriate printed electrodes for organic semiconductor-based field effect transistors (FETs) must be chosen. Typically, printable conductive inks are silver based, which often leads to poor energy level matching with the organic semiconductor. This report will study the use of both a nanoparticle silver ink as well as a soluble silver-complex ink and will show that by modifying the surface chemistry of the printed silver, though the use of self-assembly techniques (particularly thiol chemistry), the work function and wetting characteristics of the electrodes can be tailored. Combining these modified electrodes with organic semiconductors such as 6,13-bis(triisopropyl-silylethynyl) pentacene (TIPS-pentacene) yields high performance devices with field-effect mobilities > 0.5 cm2 V-1 s-1.
