Fabrication of Superconducting Nanowires Using the Template Method

Abstract

The fabrication and characterization of superconducting nanowires fabricated by the anodic aluminium oxide (AAO) template technique has been reviewed. This templating method was applied to conventional metallic superconductors, as well as to several high-temperature superconductors (HTSc). For filling the templates with superconducting material, several different techniques have been applied in the literature, including electrodeposition, sol-gel techniques, sputtering, and melting. Here, we discuss the various superconducting materials employed and the results obtained. The arising problems in the fabrication process and the difficulties concerning the separation of the nanowires from the templates are pointed out in detail. Furthermore, we compare HTSc nanowires prepared by AAO templating and electrospinning with each other, and give an outlook to further research directions.

Synthesis of nickel nanowires (Ni-NWs) as high ferromagnetic material by electrodeposition technique

“…The AAO template is one of the widely used templates for the deposition of metal NWs because it has an advantage to exactly control the diameter of NWs which has been confirmed by the pore size of templates [ 25 , 26 , 27 ].…”

Incorporation of Ions into Nanostructured Anodic Oxides—Mechanism and Functionalities

“…An impressive amount of research on anodic alumina provides progress in nanofabrication [19] of materials with emerging applications-like biomimetic materials [20], CO 2 conversion [21], energy storage [22], or superconductive materials [23]-and stimulates research on the anodization of other metals. The most significant applications of nanostructured oxides formed by the anodization of popular metals are presented in Figure 2.…”
