| Outline of Final Research Achievements |
In this work, a photo-active superconducting device by laminating a thin-single crystal of κ-Br on the substrate covered with a self-assembled monolayer of spiropyran-derivatives have been fabricated. As a result, reversible light-induced electron- or hole-doping into κ-type BEDT-TTF salts and accompanying superconducting transition have been realized by UV and visible light irradiation. We demonstrated that the polarity and the density of photo-induced mobile carriers can be systematically controlled by designing the dipole moment variation of photo-active monolayers. The present results will provide new possibilities for novel photo-electronics, in which both the magnitude and the direction of photo-induced built-in potential can be designed as we like by interface molecular engineering.
