Organic TFTs: Solution-processable small-molecule semiconductors

Abstract

Organic semiconductor (OSC) materials are seen as a potential replacement for amorphous silicon in future display applications. State-of-the-art small-molecule OSC materials, when incorporated into a transistor, obtain performance on par or superior to transistors using amorphous silicon. Higher performance coupled with the potential for low-cost fabrication make small-molecule OSC materials extremely promising and the focus of research organizations worldwide. This chapter provides an overview of p-type and n-type materials available, then addresses the impact of processing conditions on transistor performance, and finally concludes with an overview of state-of-the-art materials.
