| Abstract(in English) | An organic transistor is one of candidates of a transistor for operating organic EL devices. Application of an organic transistor to organic EL devices requires low-voltage and high-output-current operation. An organic transistor, a gate insulator layer of which is replaced with ionic liquid or electrolyte, controls a high output current at a low voltage compared to a general organic field effect transistor(OFET). It is necessary to elucidate the operation mechanism for improvement of the performance of the organic transistor using ionic liquid. In this study, the generation of carriers in a P3HT layer was in-situ observed using infrared absorption spectroscopy in the multiple internal reflection geometry(MIR-IRAS)and the potential distribution between source and drain electrodes was measured. The penetration of anions of ionic liquid into a P3HT layer was observed in infrared absorption spectra, indicating that the electrochemical doping into P3HT layer took place. The potential was concentrated near the drain electrode. These results indicate that the transistor was controlled by electrochemical doping into a P3HT layer near the drain electrode. |
