我们在金包覆的硅衬底上成功制备了致密且均匀的六方纤锌矿结构的ZnS纳米线。单晶 ZnS 纳米线的生长遵循众所周知的气液固 (VLS) 机制。通过原子力显微镜 (AFM) 研究了金颗粒上 ZnS 纳米颗粒的成核和生长过程的初始阶段，以深入了解促进纳米线生长的临界核尺寸。 AFM 图像清楚地显示了 VLS 生长过程的三个阶段。微拉曼散射检测与 ZnS 纳米线的纳米尺寸效应相关的各种峰值。 (C) 2004 Elsevier B.V. 保留所有权利。
We have successfully prepared dense and uniform ZnS nanowires with hexagonal wurzite structure on Au-coated Si substrate. The growth of the single crystalline ZnS nanowire follows the well-known vapor liquid solid (VLS) mechanism. The initial stages of the nucleation and growth processes of ZnS nano-particles on gold particles have been studied by atomic force microscopy (AFM) to derive insights into the critical nuclei size that promoted the growth of the nanowire. AFM images clearly show the three stages of the VLS growth process. Micro-Raman scattering detects various peaks related to the nanosize effects of the ZnS nanowires. (C) 2004 Elsevier B.V.
