Nanopeapods by Galvanic Displacement Reaction

Abstract

Like peas in a pod: Galvanic displacement of electrodeposited multisegmented nanowires was used to synthesize nanopeapod structures at room temperature (see scheme). Depending on the redox potential of the displacement process, a variety of nanopeapod materials could be prepared, e.g., semiconductor/metal, p-type/n-type, metal/metal, ferromagnetic/nonmagnetic materials.
