From: Co nanoparticle hybridization with single-crystalline Bi nanowires
Schematic illustration for the process of forming Co nanoparticles on the surface of Bi nanowires. Bi nanowires are first grown by the OFF-ON method and they are subsequently coated with a thin Co film by in situ sputtering. Co nanoparticles are finally formed on the surface of Bi nanowires via post-annealing at elevated temperatures.
