ABSTRACT
Single-crystalline Zn/ZnS coaxial nanocables were fabricated through thermal reduction of ZnS using graphite powder at elevated temperatures. Energy dispersive x-ray analysis of the as-fabricated samples indicated that the nanowires were composed of Zn and S only. Transmission-electron-microscopic study of the nanowires revealed that they had core/sheath contrast, suggesting a Zn core/ZnS sheath heterostructure. Epitaxial relationship was observed between the Zn and the ZnS. The possible formation mechanisms of such nanocables are discussed.

    The structural trends in ZnO, ZnS, and ZnSe nanowires (NWs) are investigated by using our empirical potential based on a simple approach. The calculated NW cohesive energy shows that the stabile crystal structure of ZnS and ZnSe NWs depends on the nanowire diameter while ZnO NWs always takes the...
