Printable organic and polymeric semiconducting materials and devices

Solution-processable organic and polymeric semiconducting materials are act ive materials used for electronic devices such as thin film field-effect tr ansistors (FETs). These materials are more likely to have practical advanta ges when coupled with low cost approaches to patterning that are compatible with them. Material requirements for high performance solution based FETs are discussed. Also described are structural, morphological, and processing factors that influence device performance. Finally, methods and schemes of printing workable devices are surveyed.
