| Outline of Final Research Achievements |
Previously, reversible photoswitching of magnetization has been present by interfacing photoresponsive compounds. This strategy could apply to other properties by the appropriate integration of photoresponsive compounds and functional materials. First, superconducting properties of diamond were compared between hydrogen- and oxygen-termination. The critical current density was larger in the H-termination, compared to the O-one, which were reversibly modulated through surface modification. Then, a photoswitchable superconductor was prepared and characterized, in which a photochromic azobenzene molecular layer was immobilized onto the superconducting diamond. The critical current density was controlled reversibly upon photoisomerization of an azobenzene molecule. This effect is explained as the reversible photoisomerization inducing an inhomogeneous electron distribution along the superconducting diamond surface.
