| Outline of Final Research Achievements |
A main purpose of this study is to develop a vertical tunnel transistor. Key component of this device is binary molecular monolayers, which were incorporated in a double-tunneling junction to work as quantum dots for electron tunneling. An advantage of organic molecules is that energy levels of molecules can be tuned precisely by designing molecular structures. In fact, we observed multi-step tunneling in accordance with the energy levels of respective molecules. Furthermore, electron-tunneling can be modulated under side-gate bias voltages. Thus, vertically-aligned tunneling transistor with multi-value switching operation were successfully developed by using organic molecules.
