  • Patent number: 11974508
    Abstract: According to various implementations of the invention, a vertical Josephson Junction device may be realized using molecular beam epitaxy (MBE) growth of YBCO and PBCO epitaxial layers in an a-axis crystal orientation. Various implementations of the invention provide improved vertical JJ devices using SiC or LSGO substrates; GaN, AlN, or MgO buffer layers; YBCO or LSGO template layers; YBCO conductive layers and various combinations of barrier layers that include PBCO, NBCO, and DBCO. Such JJ devices are simple to fabricate with wet and dry etching, and allow for superior current flow across the barrier layers.

  • Patent number: 11930722
    Abstract: Operational characteristics of an high temperature superconducting (“HTS”) film comprised of an HTS material may be improved by depositing a modifying material onto appropriate surfaces of the HTS film to create a modified HTS film. In some implementations of the invention, the HTS film may be in the form of a “c-film.” In some implementations of the invention, the HTS film may be in the form of an “a-b film,” an “a-film” or a “b-film.” The modified HTS film has improved operational characteristics over the HTS film alone or without the modifying material. Such operational characteristics may include operating in a superconducting state at increased temperatures, carrying additional electrical charge, operating with improved magnetic properties, operating with improved mechanic properties or other improved operational characteristics. In some implementations of the invention, the HTS material is a mixed-valence copper-oxide perovskite, such as, but not limited to YBCO.

  • Patent number: 9431156
    Abstract: In some implementations of the invention, existing extremely low resistance materials (“ELR materials”) may be modified and/or new ELR materials may be created by enhancing (in the case of existing ELR materials) and/or creating (in the case of new ELR materials) an aperture within the ELR material such that the aperture is maintained at increased temperatures so as not to impede propagation of electrical charge there through. In some implementations of the invention, as long as the propagation of electrical charge through the aperture remains unimpeded, the material should remain in an ELR state; otherwise, as the propagation of electrical charge through the aperture becomes impeded, the ELR material begins to transition into a non-ELR state.

  • Patent number: 9431594
    Abstract: The invention pertains to creating new extremely low resistance (“ELR”) materials, which may include high temperature superconducting (“HTS”) materials. In some implementations of the invention, an ELR material may be modified by depositing a layer of modifying material unto the ELR material to form a modified ELR material. The modified ELR material has improved operational characteristics over the ELR material alone. Such operational characteristics may include operating at increased temperatures or carrying additional electrical charge or other operational characteristics. In some implementations of the invention, the ELR material is a cuprate-perovskite, such as, but not limited to BSCCO. In some implementations of the invention, the modifying material is a conductive material that bonds easily to oxygen, such as, but not limited to, chromium.
