| Outline of Final Research Achievements |
Organic field-effect transistors show light emission when electrons and holes are simultaneously injected. Because a high current density can be realized in single-crystalline organic semiconductors, it is expected as a promising device structure for current-injection organic laser. However, because there is a trade-off between carrier mobilities and a fluorescence efficiency in an organic semiconductor. In this study, the difficulty was overcome by developing a new device structure, which has a bilayer single-crystalline organic semiconductor, which consists of an organic semiconductor with high carrier mobility and another organic semiconductor with high fluorescence efficiency.
