摘要

摘要本文介绍了使用金催化剂，通过化学气相沉积法在硅基底上生长具有相变和可控直径的 Sb2Te3 瑀纳米线的结果。除了金催化剂的尺寸外，初始 Sb2Te3 粉末的量也可用于控制 Sb2Te3 纳米线的直径。Sb2Te3 纳米线的直径明显随着金催化剂尺寸和 Sb2Te3 粉末量的增加而增大。通过有效控制金纳米粒子的尺寸和 Sb2Te3 粉末的用量，Sb2Te3 纳米线的直径可控制在 145 至 275 nm 的大范围内。根据吉布斯-汤姆逊效应，从过饱和的角度详细揭示了金纳米粒子的大小和 Sb2Te3 粉末的用量对 Sb2Te3 纳米线直径的影响。

Diameter-Controlled Growth of Sb2Te3 Nanowires with Au Catalyst by the Vapor–Liquid–Solid Mechanism

This paper presents the results of growing chalcogenide nanowires of Sb₂Te₃ with a phase transition and a controlled diameter on Si substrates by the chemical vapor deposition method using an Au catalyst. In addition to the size of the Au catalyst, the amount of the initial Sb₂Te₃ powder is also used to control the diameter of Sb₂Te₃ nanowires. The diameter of the Sb₂Te₃ nanowires clearly increases with both the size of the Au catalyst and the amount of the Sb₂Te₃ powder. By effectively controlling the size of Au nanoparticles and the amount of the Sb₂Te₃ powder, the diameter of the Sb₂Te₃ nanowires can be controlled in a wide range from 145 to 275 nm. The influence of the size of Au nanoparticles and the amount of the Sb₂Te₃ powder on the diameter of the Sb₂Te₃ nanowires is revealed in terms of supersaturation, based in detail on the Gibbs–Thomson effect.
