Superconducting Electronics Applications

Fortunately, there are now better ways to assess the inner state of our bodies cameras that make x-ray seem almost like a relic of the days of saddlebag doctors. These new devices rely on the dramatic advances in solid-state electronics and computer technology and on vastly improved knowledge of sound waves, infrared sources, the protons in the nuclei of hydrogen atoms, radio waves, magnetism, and in many applications, superconductivity.

Technological applications of superconductivity can be divided into two major areas superconducting electronics and superconducting wires and tapes. While the widespread use of high-Tc cuprate superconductors in technology has not yet been realized, steady and... 

Nb/oxide/Nb, Nb/a-Si/Nb, and NbN/oxide/NbN junction processes were proposed by IBM (1), Sperry (2), and ETL (3), respectively. Some preliminary work on an integrated device succeeded with these processes. After that, an Nb/AlO /Nb junction process was proposed by AT T (4). This process is widely used in the field of superconducting electronics. Many researchers have obtained fine results in application work on a superconducting device. 

Electrical and Electronic Applications. Silver neodecanoate [62804-19-7] has been used in the preparation of a capacitor-end termination composition (110), lead and stannous neodecanoate have been used in circuit-board fabrication (111), and stannous neodecanoate has been used to form patterned semiconductive tin oxide films (112). The silver salt has also been used in the preparation of ceramic superconductors (113). Neodecanoate salts of barium, copper, yttrium, and europium have been used to prepare superconducting films and patterned thin-fHm superconductors. To prepare these materials, the metal salts are deposited on a substrate, then decomposed by heat to give the thin film (114—116) or by a focused beam (electron, ion, or laser) to give the patterned thin film (117,118). The resulting films exhibit superconductivity above Hquid nitrogen temperatures. 

No superconductivity has yet been found in carbon nanotubes or nanotube arrays. Despite the prediction that ID electronic systems cannot support supercon-ductivity[33,34], it is not clear that such theories are applicable to carbon nanotubes, which are tubular with a hollow core and have several unit cells around the circumference. Doping of nanotube bundles by the insertion of alkali metal dopants between the tubules could lead to superconductivity. The doping of individual tubules may provide another possible approach to superconductivity for carbon nanotube systems.
