(Source: Tokyo Institute of Technology) An applied potential can reversibly induce a superconducting-insulator transition in lithium titanate thin films, report researchers at Tokyo Institute of Technology. 'Controlling such exotic properties by applying an external field is one of the biggest continuous challenges in condensed matter physics,' state Kohei Yoshimatsu and his colleagues in their recent paper. Their latest results demonstrate that in thin-film structures it is possible to control the transition between superconducting and insulating states using lithium ion electrochemical reactions. Observations of a transition between a superconducting and insulating state in certain...
