| Abstract(in English) | Recently, organic thin film transistors (OTFTs) are widely studied because they have a potential to realize a flexible, light-weight and large-area devices and it is expected that they are applied to an organic electroluminescence display. High current or high frequency operation of an OTFT requires further improvement of its performance. Miniaturization is important for improvement of the performance of an OTFT. In general, the sham mobility is reduced by influence of a carrier injection phenomenon at the metal/organic layer interface and the expected performance is not realized even if the channel length is narrowed. In this study, a molecular doping technique was applied to fabrication of an OTFT which was independent of the carrier injection phenomenon. The influence of the molecular doping on carrier injection phenomenon was characterized by the displacement current measurement (DCM), and it was found that the carrier injection phenomenon did not take place at the interface between highly-doped and non-doped organic layers. In addition, the doping mechanism was investigated using infrared spectroscopy in the multiple internal reflection geometry (MIR-IRAS). Finally, we fabricated an OTFT in which source and drain electrodes were formed by doping layers and demonstrated its operation as a field effect transistor. |
