The advance in superconducting microdevice technologies over the past couple of decades has shown promise for practical applications of quantum computers and superconducting photon detectors for far-IR telescopes and optical communications. One of the key factors limiting the current technology lies in the small gap and limited kinetic inductance of superconducting materials being used....
The 1144 phase (Ae1A1Fe4As4) shows a strong advantage of engineering fabrication among Fe (Iron)-based superconductor (FBS) family due to the robustness of its superconducting properties with respect to chemical inhomogeneities, granted by its uniform crystalline-layered structure. This regularity is furthermore associated to crystalline defects capable of acting as efficient pinning centers,...
Iron-based superconducting wires and tapes, particularly 122-type, based on the powder-in-tube method are promising for high-field magnet applications. A promising design is to use silver/copper composite as the sheath material (i.e., Ag is in direct contact with the IBS powder for minimum reaction while Cu is used as the outer matrix to reduce conductor cost and increase the mechanical...
Epitaxial growth and studies on “emergent behaviors” of cuprate oxide thin film heterostructures are of the utmost importance for developing many superconductor electronic devices such as Josephson junctions, three-terminal devices, and circuit applications such as interconnects, ground planes, and multichip modules. In particular, the heterostructures made with high critical temperature (Tc)...
