Latest Patents

Yiyuan Xie holds a patent for "Thin film Hg-based superconductors, thermoelectric materials and methods of fabrication thereof." This patent describes improved Hg-containing superconducting films and thermoelectric materials. The films are fabricated by annealing starting Tl-containing films, such as Tl-1212 or Tl-2212, in an Hg-vapor environment. This process allows for the substitution of Tl by Hg without significantly altering the crystalline structure of the starting films. The final Hg-containing film products exhibit a critical current density (J) of at least about 10 A/cm at 100 K and an X value of up to about 50%. The thermoelectric materials are prepared by perturbing a crystalline precursor, which leads to the release of a first molecule, followed by the introduction of a vapor to replace these molecules.
