Flow-enabled self-assembly of large-scale aligned nanowires.

Macroscopic highly aligned DNA nanowires created by controlled evaporative self-assembly.

By subjecting DNA aqueous solution to evaporate in a curve-on-flat geometry that was composed of either a spherical lens or a cylindrical lens situated on a flat substrate, a set of highly aligned DNA nanowires in the forms of spokes and parallel stripes over a macroscopic area (i.e., millimeter scale) were successfully created. The DNA molecules were stretched and aligned on polymer-coated sub...

Ordering of Disordered Nanowires: Spontaneous Formation of Highly Aligned, Ultralong Ag Nanowire Films at Oil–Water–Air Interface

One-dimensional nanomaterials and their assemblies attract considerable scientific interest in the physical, chemical, and biological fields because of their potential applications in electronic and optical devices. The interfaceassembly method has become an important route for the self-assembly of nanoparticles, nanosheets, nanotubes, and nanorods, but the self-assembly of ultralong nanowires ...

A nanoscale combing technique for the large-scale assembly of highly aligned nanowires.

The controlled assembly of nanowires is a key challenge in the development of a range of bottom-up devices. Recent advances in the post-growth assembly of nanowires and carbon nanotubes have led to alignment ratios of 80-95% for a misalignment angle of ±5° (refs 5, 12, , 14) and allowed various multiwire devices to be fabricated. However, these methods still create a significant number of cross...

Understanding self-aligned planar growth of InAs nanowires.

Semiconducting nanowires have attracted lots of attention because of their potential applications. Compared with free-standing nanowires, self-aligned planar nanowires grown epitaxially on the substrate have shown advantageous properties such as being twin defect free and ready for device fabrication, opening potentials for the large-scale device applications. Understanding of planar nanowire g...
