Research on organic electronics (or plastic electronics) is driven by the need to create low-cost electronic devices that are lightweight, mechanically robust and structurally flexible. With the remarkable improvement in the performance of organic electronic materials during the past decade, organic electronics now appeal to innovative, practical, and broad-based applications requiring large-area coverage, lightweight and mechanical flexibility, which range from large-area and flexible displays to sensors, images, electronic identification and security tracking devices. This book presents a comprehensive investigation of the production and application of a variety of polymer based transistor devices and circuits. It begins with a detailed overview of Organic Thin Film Transistors (OTFTs) and discusses the various possible fabrication methods reported so far. This is followed by two major sections on the choice, optimization and implementation of the gate dielectric material. Details of the effects of processing on the efficiency of the contacts are then provided. The book concludes with a chapter on the integration of such devices to produce a variety of OTFT based circuits and systems.
