Synthesis of cobalt metal nanowire arrays and the interfacial reactions of cobalt nanowires on (001)Si

Abstract

In this study, we report the successful synthesis of large-scale, well-aligned pure cobalt metal nanowire arrays by using the electrodeposition in conjunction with anodic aluminum oxide (AAO) templates technique, and the investigation of the interfacial reactions between the produced Co metal nanowires and (001)Si substrate after different heat treatments. The morphologies, crystal structures, and compositions of the as-synthesized Co nanowires and the Co silicide nanostructures obtained after annealing at various temperatures were systematically investigated by SEM, TEM, and electron diffraction analyses.

Synthesizing Cu-Sn nanowires alloy in highly-ordered Aluminum Oxide templates by using electrodeposition method

“…7(b), it is shown that the cystalline structure of nanowires is a mixture of unreacted crystalline Sn and η−Cu 6 Sn 5 intermetallic compound. Due to conventional DC electrochemical deposition procedures, the growth of intermetallic compounds needs a post heat treatment step to facilitate the re-nucleation and growth of crystalline structures [65][66][67][68][69][70][71][72][73]. As a result, the observed intermetallic compound (η−Cu 6 Sn 5 , cref.…”
