Outline of Final Research Achievements |
In the current research project, I have developed the photofunctional material, where superconducting properties could be modulated upon photochemical reaction. First, I have examined the superconducting properties of a boron-doped diamond (BDD). As surface termination of BDD can be easily modified by chemical reactions, I have especially examined the superconducting properties of hydrogen- and oxygen-terminated BDD (denoted as H- and O-BDD). Critical current density was reversibly modulated between H- and O-BDD, derived from changes in the superconducting volume fraction. Next. I have fabricated a hybrid superconductor composed of BDD and a photochromic azobenzene compound (denoted as AZ-BDD). In AZ-BDD, critical current density was reversibly modulated upon photoisomerization of AZ. The photochromism-induced amplification of critical current density was about 55 % that was 4 times larger than the previous report.
