Organic Electronic Materials and Devices

Abstract

Organic semiconductors that were discovered more than half century ago in Japan (H. Inokuchi, Org. Electron. 7, 62 (2006)) are now transfigured into the practicable electronic materials by the recent concentrated studies of the materials, thin-film processing, and device fabrication technologies. In this chapter, we first present and discuss fundamental aspects of electronic phenomena in organic semiconductors as the bases to understand and study the organic electronics technologies. Then we discuss how to understand the charge-carrier transport in organic field-effect transistors (or more frequently refferd as organic thin-film transistors, or OTFTs). Finally we introduce recent studies to fabricate OTFTs by print production technologies.
