| Abstract(in English) | The carrier behavior inside the grain and at the grain boundary of TIPS pentacene field effect transistor (FET) was studied by the time-resolved microscopic second harmonic generation (TRM-SHG) measurement. Under the pulse voltage operation of the organic FET (OFET), time-evolution of the electric field distribution along the channel is observed by changing the delay time between laser pulses and voltage pulses that drive OFET. Under the positive pulse application to the source electrode, holes are injected from source electrode and are transported along the channel. According to the carrier transport, emission band of SHG signal, which is visualized by the cooled CCD, gradually moves in the channel from source to drain electrode with an increase in delay time. In the TIPS pentacene FET, it was found that the carrier transport was smooth inside the grain; on the other hand, it was inhibited at the grain boundary. Potential drop was clearly observed at the grain boundary. After turning off the voltage, SHG emission at the boundary was remained, indicating carriers are trapped at the grain boundary. |
