Research Abstract

In this study, the influence of molecular fluctuation on the transport mechanism of organic transistors have been investigated. Hall effect measurements on n-type and various materials have been successfully measured. And Hall effect measurements under high pressure has been performed. Under high pressure, electronic overlap between adjacent molecules are increased and molecular fluctuation are suppressed, as a result, the mechanism of charge transport closed to clear band transport.
As for the development of high-mobility organic transistors, high-mobility material as high as 16 cm2/Vs has been developed thorough good collaborating research. The materials are designed based on the concept which comes out from this study. This result demonstrate the usefulness of the concept developed by this study. And finally, world's fastest switching organic transistors have been successfully developed in this study.
