Latest Patents

Yves J Lepetre holds a patent for a "Superconducting structure with layers of niobium nitride and aluminum." This patent describes a superconducting structure formed by depositing alternate layers of aluminum nitride and niobium nitride on a substrate. The deposition methods include dc magnetron reactive sputtering, rf magnetron reactive sputtering, thin-film diffusion, chemical vapor deposition, and ion-beam deposition. The structures have been built with layers of niobium nitride and aluminum nitride having thicknesses ranging from 20 to 350 Angstroms. The best results have been achieved with films of niobium nitride deposited to a thickness of approximately 70 Angstroms and aluminum nitride deposited to a thickness of approximately 20 Angstroms. Such films of niobium nitride, separated by a single layer of aluminum nitride, are useful in forming Josephson junctions. Structures with 30 or more alternating layers of niobium nitride and aluminum nitride are beneficial when deposited on fixed substrates or flexible strips to create bulk superconductors for carrying electric current. They are also adaptable as voltage-controlled microwave energy sources.
