Semiconducting inorganic nanowires (NWs), nanotubes and nanofibers have been extensively explored in recent years as potential building blocks for nanoscale electronics, optoelectronics, chemical/biological/optical sensing, and energy harvesting, storage and conversion, etc. Besides the top-down approaches such as conventional lithography technologies, nanowires are commonly grown by the bottom-up approaches such as solution growth, template-guided synthesis, and vapor-liquid-solid process at a relatively low cost. Superior performance has been demonstrated using nanowires devices. However, most of the nanowire devices are limited to the demonstration of single devices, an initial step toward nanoelectronic circuits, not adequate for production on a large scale at low cost. Controlled and uniform assembly of nanowires with high scalability is still one of the major bottleneck challenges towards the materials and device integration for electronics. In this review, we aim to present recent progress toward nanowire device assembly technologies, including flow-assisted alignment, Langmuir-Blodgett assembly, bubble-blown technique, electric/magnetic- field-directed assembly, contact/roll printing, planar growth, bridging method, and electrospinning, etc. And their applications in high-performance, flexible electronics, sensors, photovoltaics, bioelectronic interfaces and nano-resonators are also presented.
近年来，半导体无机纳米线（NWs）、纳米管和纳米纤维作为纳米电子学、光电学、化学/生物/光传感以及能量收集、存储和转换等领域的潜在构建模块得到了广泛的研究。除了自上而下的方法，如传统光刻技术，纳米线通常通过自下而上的方法，如溶液生长、模板引导合成和汽液固过程，以相对较低的成本生长。使用纳米线器件已经展示了优异的性能。然而，大多数纳米线器件仅限于单个器件的演示，这是迈向纳米电子电路的第一步，不足以进行大规模、低成本的生产。具有高可扩展性的纳米线的可控和均匀组装仍然是电子材料和器件集成的主要瓶颈挑战之一。在这篇综述中，我们旨在介绍纳米线器件组装技术的最新进展，包括流动辅助对准、Langmuir-Blodgett 组装、气泡吹制技术、电场/磁场定向组装、接触/滚动印刷、平面生长、桥接方法和静电纺丝等。并介绍了它们在高性能、柔性电子、传感器、光伏、生物电子接口和纳米谐振器中的应用。
