New method for superconductor exploration using electric field


  Division of Low Temperature Condensed State Physics, in collaboration with International Advanced Research and Education Organization, establish a simple method to search for new superconductors by applying a voltage to materials. Despite the world-first realization of voltage-induced superconductivity last year by an IMR/WPI-AIMR collaboration, this method still has been limited to one specific material. Here, we introduced ionic liquids, which significantly broadened the variety of materials and succeeded in increasing Tc from last year’s 0.4 K to 15 K. This achievement was published in Nature Materials (AOP, 22nd Nov.), and was reported in NHK-TV (23rd), Mainichi, Kahoku Shimpo, and other newspapers (24th).
