Paul Canfield has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Low resistivity contact to iron-pnictide superconductors
    Patent number: 8450246
    Abstract: Method of making a low resistivity electrical connection between an electrical conductor and an iron pnictide superconductor involves connecting the electrical conductor and superconductor using a tin or tin-based material therebetween, such as using a tin or tin-based solder. The superconductor can be based on doped AFe2As2, where A can be Ca, Sr, Ba, Eu or combinations thereof for purposes of illustration only.
    Type: Grant
    Filed: February 15, 2011
    Date of Patent: May 28, 2013
    Assignee: Iowa State University Research Foundation, Inc.
    Inventors: Makariy Tanatar, Ruslan Prozorov, Ni Ni, Sergey Bud'ko, Paul Canfield

  • SUBSTRATE AND METHOD FOR THE FORMATION OF CONTINUOUS MAGNESIUM DIBORIDE AND DOPED MAGNESIUM DIBORIDE WIRES
    Publication number: 20080056976
    Abstract: A chemically doped boron coating is applied by chemical vapor deposition to a silicon carbide fiber and the coated fiber then is exposed to magnesium vapor to convert the doped boron to doped magnesium diboride and a resultant superconductor.
