Great effort has been applied to scientific research on the controllable synthesis of carbon nanotubes (CNTs) with high semiconducting selectivity or high areal density toward the macroscale applications of high-performance carbon-based electronics. However, the key issue of compatibility between these two requirements for CNTs remains a challenge, blocking the expected performance boost of CNT devices. We report an in situ acoustic-assisted assembly of high-density monochromatic CNT tangles (m-CNT-Ts), consisting of one self-entangled CNT with a length of up to 100 mm and consistent chirality. On the basis of a minimum consumed energy model with a Strouhal number of approximately 0.3, the scale could be controlled within the range of 1 × 104 to 3 × 104 μm2 or even a larger range. Transistors fabricated with one m-CNT-T showed an on/off ratio of 103 to 106 with 4-mA on-state current, which is also the highest on-state current recorded so far for single CNT-based transistors. This acoustic-assisted assembly of chiral-consistent m-CNT-Ts will provide new opportunities for the fabrication of high-performance electronics based on perfect CNTs with high purity and high density.

用于高导通电流晶体管的单个单色超长碳纳米管的声学辅助组件。
在高性能碳基电子学的大规模应用中，已经进行了巨大的努力，用于具有高半导体选择性或高面密度的可控制合成碳纳米管（CNT）的科学研究。但是，这两个对CNT的要求之间兼容性的关键问题仍然是一个挑战，阻碍了CNT器件预期的性能提升。我们报告了高密度单色CNT缠结（m-CNT-Ts）的原位声波辅助组件，该组件由一根长度最大为100 mm的自纠缠CNT和一致的手性组成。上具有大约0.3的Strouhal数的最小消耗的能量模型的基础上，所述标尺可以为1×10的范围内被控制4〜3×10 4微米2甚至更大的范围。用一个m-CNT-T制造的晶体管的导通/截止比为10 3至10 6，导通电流为4 mA，这也是迄今为止基于单个CNT的晶体管记录的最高导通电流。这种手性一致的m-CNT-T的声音辅助组装将为制造基于具有高纯度和高密度的完美CNT的高性能电子设备提供新的机会。
