Abstract The main challenge for application of solution-derived carbon nanotube (CNT) in high performance field-effect transistor is how to obtain the aligned film with full surface coverage and uniform inter-tube pitch. Herein, a wafer-scale aligned array of s-SWCNTs can be assembled using the combination of the introduced inter-tube electrostatic repulsion and an improved “bi-phasic” dip-coating method. By using a conjugated molecule with positive charge to modify the charge on the surface of s-SWCNTs dispersed in organic solvents, the inter-tube electrostatic repulsion was correspondingly introduced. The inter-tube electrostatic repulsion can significantly inhibit the agglomeration of s-SWCNTs in the formation process of the aligned SWCNT films. Significantly, the aligned SWCNT thin film exhibits excellent surface coverage and anisotropy over the 3 inch aligned area.

通过引入管间静电排斥在有机溶剂中组装排列的半导体碳纳米管

摘要 溶液衍生碳纳米管（CNT）在高性能场效应晶体管中的应用面临的主要挑战是如何获得具有全表面覆盖和均匀管间距的取向膜。在这里，可以使用引入的管间静电排斥和改进的“双相”浸涂方法的组合来组装晶片级对齐的 s-SWCNT 阵列。通过使用带正电荷的共轭分子来修饰分散在有机溶剂中的s-SWCNTs表面的电荷，相应地引入了管间静电排斥。管间静电排斥可以显着抑制s-SWCNTs在取向SWCNT薄膜形成过程中的团聚。显着地，
