Printed Organic Semiconducting Devices

Abstract
Recent improvements in carrier mobility, environmental stability, and advancements in p- and n-type organic semiconductor materials have resulted in reports of device operation suitable for low-functionality, low-cost products. Deposition of solution-processable materials that enable the use of low-cost, high-speed deposition techniques such as screen printing, spin coating, and conventional graphic arts printing technologies have also recently been demonstrated. The material requirements necessary to realize these products, an organic transistor device structure that can be fabricated with these materials via printing processes, and the resulting device performance are presented and discussed. The use of standards and their impact on driving technology to commercialization are also addressed.
