摘要
We have developed a process for chemical purification of carbon nanotubes for solution-processable thin-film transistors （TFTs） having high mobility. Films of the purified carbon nanotubes fabricated by simple drop coating showed carrier mobilities as high as 164 cm2V-1s -1 normalized transconductances of 0.78 Sm-1 and on/off current ratios of 10^6. Such high performance requires the preparation of a suspension of micrometer-long and highly purified semiconducting single-walled carbon nanotubes （SWCNTs）. Our purification process includes length and electronic-type selective trapping of SWCNTs using recycling gel filtration with a mixture of surfactants. The results provide an important milestone toward printed high-speed and large-area electronics with roll-to-roll and ink-jet device fabrication.
我们为 solution-processable 为碳 nanotubes 的化学纯化开发了一个过程有高活动性的薄电影的晶体管(TFT ) 。简单落下涂层制作的净化的碳 nanotubes 的电影象 164 cm2V1s1， 0.78 Sm1 的规范的跨导，和开／关电流一样高显示出搬运人活动性 106 的比率。如此的高效要求测微计长、高度净化的半导体的围单人赛的碳 nanotubes (SWCNT ) 的暂停的准备。我们的纯化过程包括长度并且用与表面活化剂的混合物再循环胶化过滤的 SWCNT 的电子类型的选择套住。结果提供一个重要里程碑向与 roll-to-roll 和墨水喷气设备制造打印了高速度、大区域的电子学。
