In this study, we synthesized various dimensionalities of ZnO nanowires using the Ti grid-assisted chemical vapor deposition process. Energy dispersive X-ray spectroscopic mapping technique accompanied with a lattice diffusion model was used to characterize the growth mechanism. A diffusion ratio γ, defined by short-circuit and lattice diffusion activation energies, was obtained to describe the growth mechanism of ZnO nanowires. The tunable dimensionalities of ZnO nanowires allow us to modify the morphology of ZnO nanocrystals by developing well-controlled potential applications.
在这项研究中，我们使用 Ti 网格辅助化学气相沉积工艺合成了各种维度的 ZnO 纳米线。采用能量色散 X 射线能谱映射技术和晶格扩散模型对其生长机制进行了表征。通过短程和晶格扩散激活能定义的扩散比 γ，描述了 ZnO 纳米线的生长机制。ZnO 纳米线的可调维度使我们能够通过开发良好控制的潜在应用来修改 ZnO 纳米晶体的形态。
