| Abstract(in English) | Controlling of interface between organic semiconductor and metal electrode is key issue to improve in the characteristics of organic static induction transistors (OSITs). Because carrier was injected from the source electrode thorough the interface and was restricted around gate electrode. In this study, we focused on the interface control of OSIT such as hole injection barrier at source electrode and Schottky barrier at gate electrode for improvement in the characteristics of OSITs. In pentacene based OSITs fabricated on CuPc/ITO and ITO, the electronic structure and the device characteristics were measured by ultraviolet photoelectron spectroscopy (UPS) and semiconductor parameter analyzer in order to investigate the dependence of the electronic structure on the device characteristics. In CuPc based OSITs with and without oxide layer around Al gate electrode, the device characteristics were measured to investigate the effect of the oxide layer on the device characteristics. We also investigated the device characteristics of CuPc based OSITs and compared with the calculation results obtained by two-dimensional (2D) device simulator. The obtained results showed that a high performance OSITs with high On/Off ratio was obtained by interface control of organic semiconductor/source electrode and deposition of oxide layer around Al gate with narrow gap. |
