Template‐Free Growth of High‐Temperature Superconductor Nanowires

As devices become ever smaller and more efficient, the crystallochemically controlled synthesis of high-performance materials that comprise their core has attracted enormous attention. Integration complex functional into next generation electronic will require exquisite control anisotropic form, either as nanotubes, nanotapes, or nanowires, yet easy preparation abundant quantities them remains stubbornly challenging. Herein, a template-free, flux-mediated growth vast three compositions phase-pure, high-temperature superconductor including for first time, nanowires technologically important quinternary Bi2Sr2CaCu2O8+x (B2212) is demonstrated. The results this work may provide an opportunity to investigate physics chemistry highly enable incorporation nanoelectronics energy systems.
