Abstract Carbon nanotubes (CNTs) have the recorded mechanical strength, exceptionally high thermal stability close to that of diamond, and an extremely high carrier mobility, which is two orders of magnitude higher than that of silicon. A CNT can be conducting, medium or small band gap semiconducting, depending on the exact atomic configuration and the tube diameter. To realize its applications in high-end electronics and even replacing silicon in semiconductor industry, the synthesis of high-purity single-walled CNTs (SWCNTs) with unique structure (chirality) at a relatively low price, is essential. Direct synthesis of SWCNTs with the desired chirality has been one of the great challenges for more than 20 years and it is only very recently that direct synthesis of SWCNTs with purity >90% was achieved. In this review, we have summarized previous researches and state-of-the-art chirality-selective SWCNT synthesis, including experimental and theoretical studies dealing with the mechanism of SWCNT growth, potential routes toward chirality-selection during growth, and recent experimental techniques targeted toward the selective growth of high-purity SWCNTs.

单壁碳纳米管的手性控制合成——从机理研究到实验实现

摘要 碳纳米管 (CNT) 具有已记录的机械强度、接近金刚石的极高热稳定性和极高的载流子迁移率，比硅高两个数量级。CNT 可以是导电、中带隙或小带隙半导体，具体取决于确切的原子配置和管直径。为了实现其在高端电子产品中的应用，甚至在半导体工业中替代硅，以相对较低的价格合成具有独特结构（手性）的高纯度单壁碳纳米管（SWCNT）是必不可少的。20多年来，直接合成具有所需手性的单壁碳纳米管一直是一项巨大的挑战，直到最近才实现纯度>90%的单壁碳纳米管的直接合成。在这次审查中，
