| Outline of Final Research Achievements |
In order to understand the process of external control of magnetic/transport properties of materials, we have performed non-contact measurements of interfacial structures of various functional materials. Cobalt ultrathin films, which vary their Curie temperature by applied electric voltage, shows no structural change caused by the voltage. In contrast, the self assembled monolayers on electrode changes their conformation. Such structural switching caused by the external voltage is used for the control of the work function of the electrode with respect to the HOMO level of the organic semiconductor to reduce the contact resistivity. In the course of this study, we have developed a new method of the surface structure analysis based on the informatics, which helps future studies a lot.
