摘要
金刚石纳米线是一种宽禁带的半导体材料,理论研究表明金刚石纳米线具有优异的物理化学性能,如负的电子亲和势、良好的化学惰性、高的杨氏模量和极高的硬度以及室温下高的热导率。这些优异的性能让研究者产生了浓厚的兴趣,并促进了金刚石纳米线合成方法的发展。其中包括离子反应刻蚀、碳纳米管的等离子后处理、高温高压法、模板或催化剂辅助CVD法。综述了金刚石纳米线的主要制备方法有反应离子刻蚀法和化学气相沉积法以及目前金刚石纳米线的研究进展。
Diamond nanowires is a kind of wide band-gap semiconductor materials.Theoretical evaluation shows that the diamond nanowires has excellent physical and chemical properties,such as negative electron affinity,good chemical inertness,high young’s modulus and high hardness,and high thermal conductivity at room temperature.These theoretical study prompted experiments with important feasible development goals,through a lot of efforts to study,synthesis of diamond nanowires has got great development,including ion etching,plasma processing of carbon nanotubes,high temperature and high pressure method,template or catalyst assisted CVD method.This paper summarizes the main preparation methods of diamond nanowires:reactive ion etching and chemical vapor deposition method,and the research progress of diamond nanowires.
