  • High-temperature superconducting film
    Patent number: 9461233
    Abstract: A high-temperature superconducting film includes a SrTiO3 substrate, a single crystalline FeSe layer, and a protective layer with a layered crystal structure. The single crystalline FeSe layer is sandwiched between the SrTiO3 substrate and the protective layer via a layer-by-layer mode. An onset temperature of superconducting transition of the high-temperature superconducting film is greater than or equal to 54 K, and a critical current density of the high-temperature superconducting film is about 106 A/cm2 at 12 K.
    Type: Grant
    Filed: June 27, 2014
    Date of Patent: October 4, 2016
    Assignees: Tsinghua University, Institute of Physics, Chinese Academy of Sciences

  • Method for making high-temperature superconducting film
    Patent number: 9425375
    Abstract: A method for making a high-temperature superconducting film includes loading a SrTiO3 substrate in an ultra-high vacuum system. A single crystalline FeSe layer is grown on a surface of the SrTiO3 substrate by molecular beam epitaxy. A protective layer with a layered crystal structure is grown by molecular beam epitaxy and covering the single crystalline FeSe layer.
