Patents by Inventor Lynette B. Roth

Lynette B. Roth 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).

  • Improved superconductor/semiconductor junction structures
    Patent number: 4495510
    Abstract: The specification discloses a process for forming a superconductor/semiconductor junction structure having optimized low-temperature current transport properties by first providing a substrate of a chosen semiconductor material having an atomically clean surface. A layer of a first chosen superconducting material is deposited on or above the surface of the substrate to a predetermined thickness. Either before or after the formation of this layer of the first superconducting material, a region of a second chosen superconducting material is formed between the surface of the substrate and the layer of the first superconducting material to serve as an interfacial reaction barrier to prevent the reaction between the surface of the substrate and the first chosen superconducting material at the interface thereof which would otherwise result in the formation of an undesired non-superconducting material at the interface.
    Type: Grant
    Filed: November 29, 1982
    Date of Patent: January 22, 1985
    Assignee: Hughes Aircraft Company
