Research Abstract

I have successfully developed the manufacturing processes of flexible organic floating-gate transistor（Science, Vol. 326 pp. 1516-1519 (2009)）which is applicable to large-scale area-memory compatible to ambient electronics. Through the research activity, I have unveiled the mechanism of the flexible organic floating-gate transistors and its non-volatile memory effect, and successfully developed the reliable and flexible organic non-volatile memory system using organic floating-gate transistors.
