Abstract

Single-crystal aluminum (Al) nanowires (ANW) were prepared for the first time by template-based electrodeposition at room temperature. The electrolytic bath was composed of 6 M AlCl 3 and 0.2 M LiAlH 4 in tetrahydrofuran (THF). The electrodeposition was carried out inside a glovebox in a 9.999% pure nitrogen atmosphere, with less than 1 ppm moisture, and oxygen. The templates used were anodic aluminum oxide (AAO) membranes. The membranes were coated on one side with a layer of thermally evaporated Ag. X-ray diffraction (XRD) was performed on ANW arrays embedded in the AAO membrane using Cu KR radiation. The ANWs suspended in the solution obtained were cleaned by washing several times with isopropyl alcohol (IPA), alternating with centrifugal separation. Transport measurements were performed on individual nanowires using a physical properties measurement system. These measurements show that the superconducting properties of the nanowires are in agreement with expectations.
