近年来，基于液-液界面自组装技术的半导体单壁碳纳米管（s-SWCNT）晶圆级排列阵列的制造取得了重大突破。高压催化CO (HiPCO) s-SWCNT具有小直径、大带隙和多波段光学吸收的特点，在光学和电子领域都有重要的应用。然而，在组装过程中，HiPCO s-SWCNT 容易弯曲和缠结，从而增加了组装过程的复杂性。在这里，我们评估了两种界面组装方法在排列 HiPCO s-SWCNT 方面的功效，并仔细研究了这两种液-液限制系统内的界面现象。利用其中一种方法，即尺寸限制自对准，成功地在 4 英寸晶圆上制造了对准的 HiPCO s-SWCNT 阵列。实现的对准度为10.2°，HiPCO s-SWCNT的阵列密度达到每微米300-550管。这些科学发现有助于更全面地了解受限界面内非均质单壁碳纳米管的组装过程，并为小直径HiPCO s-SWCNT的光学和电子应用奠定了重要基础。

Aligned Arrays of Semiconducting HiPCO SWCNTs Prepared by Liquid–Liquid Interface Confinement Self-Assembly for Optic–Electronic Applications

In recent years, significant breakthroughs have been achieved in the fabrication of wafer-scale aligned arrays of semiconductor single-wall carbon nanotubes (s-SWCNTs) based on liquid–liquid interfacial self-assembly techniques. High pressure catalytic CO (HiPCO) s-SWCNTs, characterized by small diameters, large band gaps, and multiband optical absorption, hold significant applications in both optical and electronic domains. However, during assembly, HiPCO s-SWCNTs are prone to bending and entanglement, thereby introducing increased complexity into the assembly processes. Here, we evaluate two interfacial assembly methods for their efficacy in aligning HiPCO s-SWCNTs and scrutinize the interfacial phenomena within these two liquid–liquid confinement systems. Utilizing one of these methods, namely, dimension-limited self-alignment, aligned HiPCO s-SWCNT arrays on 4-inch wafers were successfully fabricated. The achieved alignment degree is 10.2°, and the array density of the HiPCO s-SWCNTs reached 300–550 tubes per micrometer. These scientific findings contribute to a more comprehensive understanding of the assembly process of inhomogeneous SWCNTs within confined interfaces and lay an important foundation for the optical and electronic applications of small-diameter HiPCO s-SWCNTs.
