Abstract

The reactivity of organic radicals produced by 1,1'-azobis(cyanocyclohexane) (ACN) is tuned to selectively suppress electrical conduction of small diameter single-walled carbon nanotubes, and the modified tubes are able to produce high-mobility (approximately 10 cm2 V(-1) s(-1)) and solution-processable thin-film transistors with full semiconductor device yield, promising applications in high-performance printable electronics.

摘要

通过 1,1'-偶氮双(氰基环已烷) (ACN) 产生的有机自由基的反应活性被调谐，以选择性地抑制小直径单壁碳纳米管的电传导，并且改性的管能够产生具有高迁移率（约 10 cm2 V(-1) s(-1)) 和溶液可加工的薄膜晶体管，具有全半导体器件产率，有望在高性能可印刷电子产品中得到应用。
