Development of high-performance printed polymer field-effect transistors for flexible display

AbstractThe utilization of organic conducting or semiconducting as well as printable inorganic materials as opposed to the conventional inorganic semiconductors such as silicon, among others, in the manufacture of electronics – the so-called printed electronics – revolutionized the electronic industry in the past decades as a result of their inherently unique physical properties and the new flare they brought to bear on the electronic fabrication process. This review paper provides a brief overview of the recent progress of high-performance printed polymer field-effect transistors and integrated circuits for various flexible electronic applications. It is organized into the following parts. The second section introduces π-conjugated semiconductors. It briefly introduces a variety of the best-performing π-conjugated semiconductors and their respective charge carrier mobilities in organic field-effect transistor devices. The third section presents an overview of printing techniques developed for graphical arts that can be used in the additive processing of polymer circuits. Finally, as the last part of the paper, a brief summary and perspective are presented.
