| Research Abstract |
Current technology to fabricate electronic devices is based on Si. However, recent study revealed that organic semiconductors can be utilized for making devices with totally different characteristics, such as lightweight, flexible devices. In this study, we performed structural study of interfaces to improve organic devices. High resolution, non-destructive measurements of interfaces were realized by using surface synchrotron X-ray diffraction technique. We clarified two interface structures; one is the surface structure of organic semiconductor tetracene, and the other is the electric double layer structure made of ionic liquid. The latter includes applied electric voltage dependence of the structure. Layered arrangement of the anions/cations was observed, and the ionic arrangement was controlled by the applied voltage.
