Gold/boron core-shell nanocables synthesized from gold-boron eutectic droplets.

Metal/semiconductor core-shell coaxial nanocables are promising building blocks for nanoelectronic devices while in situ growth of these nanocables remains challenging due to the distinctly different synthesis temperature ranges required for metals and semiconductors. To overcome this difficulty, we have developed a vapor-liquid-solid and oxide-assisted bimodal competition growth strategy for in situ metal/semiconductor core-shell nanocable growth. Using this process, gold/boron core-shell nanocables were obtained.
