单晶 Zn/ZnS 同轴纳米电缆是通过在高温下使用石墨粉热还原 ZnS 来制造的。对制成样品的能量色散 X 射线分析表明，纳米线仅由 Zn 和 S 组成。对纳米线的透射电子显微镜研究表明，它们具有芯/鞘对比，表明存在 Zn 芯/ZnS 鞘异质结构。观察到Zn和ZnS之间的外延关系。讨论了这种纳米电缆可能的形成机制。 (C) 2003 年美国物理研究所。
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. (C) 2003 American Institute of Physics.
