战略引入的缺陷可以用来修改碳纳米管的新性能和功能。例如,化学缺陷可以作为电子、空穴、电子空穴对甚至分子和离子的原子陷阱。控制这些缺陷在碳纳米管上的位置的能力可以使大量的基础研究和成像,传感,疾病诊断和量子信息科学的潜在应用成为可能。然而,目前还没有有效的方法来做到这一点与原子精度(-)。在本期的第535页,Linet al.report通过编程DNA链缠绕并穿过单壁碳纳米管的整个长度来创建有序的缺陷阵列。
Strategically introduced defects can be used to modify carbon nanotubes for new properties and functions. For example, chemical defects can act as atomic traps for electrons, holes, electron-hole pairs, and even molecules and ions . The ability to control the placement of these defects on carbon nanotubes could enable a plethora of fundamental studies and potential applications in imaging, sensing, disease diagnostics, and quantum information science (–). However, there is yet no effective way to do this with atomic precision (–). On page 535 of this issue, Linet al.report the creation of ordered defect arrays by programming DNA strands to wrap around and traverse the entire length of a single-walled carbon nanotube.
