“…8,10,[59][60][61][62][63][64][65][66][67][68][69] The applied electric fields can be used effectively to attract and align NWs normally by the dielectrophoresis forces, which are exerted on the dielectric NWs through the induced dipoles. 60,61 Up to now, various nanostructures, such as Au NWs, 60 Rh NWs, 9 Ag NWs, 65 Si NWs, 9 Se NWs, 65 axially modulated pn Si NWs, 67 InP NWs, 8 ZnO NWs, 62,64 CdSe NWs, 63 as well as polymer nanofibers 68 have been assembled by this approach.

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.

“…Different approaches are under investigation, such as dielectrophoresis (DEP) [19][20][21], magnetophoresis [22], Langmuir-Blodgett [23], bubble blowing [24], contact printing [25][26], and nanoscale combing [27]. DEP has been successfully proved to be a cost-effective method to trap and also to align nanoparticles [28], NWs [21,[29][30] and carbon-based nanostructures [31][32][33] between electrodes, as well as, to separate different particles [34] and cells [35][36] in microfluidic systems. Briefly, this technique relies on alternating current (AC) electric fields to align those nanostructures at specific sites through the polarizability of dielectric structures [37].…”

“…The alignment result depends on the electric voltage and frequency, as well as configurations and patterns of the electrodes. NWs have been assembled using DEP in high concentrations [59][60][61][62][63][64][65][66][67][68][69][70][71] or as individual entities [59][60][61][72][73][74]. For example, C. Chen [71] fabricated and integrated single-wall carbon nanotubes(SWCNTs) using DEP assembly, as shown in Fig.…”

Nanowires and nanotubes of diverse material compositions, properties and/or functions have been produced or fabricated through various bottom-up or top-down approaches. These nanowires or nanotubes have also been utilized as potential building blocks for functional nanodevices. The key for the integration of those nanowire or nanotube based devices is to assemble these one dimensional nanomaterials to specific locations using techniques that are highly controllable and scalable. Ideally such techniques should enable assembly of highly uniform nanowire/nanotube arrays with precise control of density, location, dimension or even material type of nanowire/nanotube. Numerous assembly techniques are being developed that can quickly align and assemble large quantities of one type or multiple types of nanowires through parallel processes, including flow-assisted alignment, Langmuir-Blodgett assembly, bubble-blown technique, electric/magnetic-field directed assembly, contact/roll printing, knocking-down, etc.. With these assembling techniques, applications of nanowire/nanotube based devices such as flexible electronics and sensors have been demonstrated. This paper delivers an overall review of directed nanowire assembling approaches and analyzes advantages and limitations of each method. The future research directions have also been discussed.
