Novel C/Cu sheath/core nanostructures synthesized via low-temperature MOCVD

Abstract

C/Cu sheath/core nanocable arrays were mass-produced on various substructures, such as Si, SiO 2, Cu or glass, by using a one-step low-temperature metal-organic chemical vapor deposition. The novel nanostructures consist of a faceted Cu nanowire core with six side surfaces and four top surfaces, and a sheath of carbon. The as-synthesized nanocables are demonstrated excellent oxidization resistance and field emission properties, and are expected to be excellent candidates as nano-interconnectors, or nanocables, in electronic devices and nano-emitters for field emissions.
