| Research Abstract |
By means of nanoscled interface control in organic field effect transistors (OFETs), we have achieved following four major achievements, all of which make important benchmarks. (1)The highest mobility of 40cm^2/Vs among organic FETs. (2)First measurement of Hall effect on OFETs. (3)First realization of ambipolar light emitting transistor of organic single crystals. (4)Highest transconductance among OFETs using the electric double layer configuration.
