| Abstract(in English) | Using pentacene field effect transistors with ferroelectric gate insulator, we studied the charge accumulation at the FET channel in terms of carrier injection and turn over of spontaneous polarization of the gate insulator. The difference of work-function of metal electrodes (Au,Al) leads to the difference in a voltage that generates the turn over of the spontaneous polarization. In the case of Al electrodes, the voltage of the turn over depends on the sweep speed of the gate voltage. This result suggests that the accumulation of holes from Al electrodes is restricted owing to the injection barrier height. |
