Outline of Final Research Achievements

The main purpose of this study is to develop multi-channel transistor for multi-level switching by using molecular nanowires as transistor channels. For this purpose, polymeric semiconductor with liquid crystal property (F8T2) was employed. One-dimensional F8T2 nanowires were fabricated by nanoimprint technique and connected common source-drain electrodes. We found that threshold voltage was controllable according to the wire diameter and carrier mobility was improved as decreasing wire diameter. These results provide basis of our target devices.
