Prof. Guy Deutscher works on fundamental and applied aspects of  superconductivity. He has focused on the properties of superconductors  near the metal to insulator transition where, surprisingly, unusually strong superconductivity is observed in materials such as oxides and  cermets, including high temperature superconductors and granular  superconductors. Another research area is the development of  superconducting tapes for power applications. The techniques used  include thin film growth, transport, tunnelling, Tera-Herz and muon  spectroscopy. Research achievements include the discovery that free  spins are present in cermet films composed of nano-scale aluminum dots  surrounded by oxide, consistent with a metal to insulator transition  that is of the Mott type and a transition from conventional  superconductivity to Bose Einstein condensation near the transition. Resonators based on such cermets have a large inductance and low losses, which is favorable for the design of elements for Quantum Computing. Another achievement is the development of superconducting  tapes composed of cuprate thin films grown on sapphire ribbons, which are very promising as basic elements of fault current limiters that  can improve network stability.
