With the extensive study of nanoelectronic devices and nanoelectromechanical systems (NEMS), nanointerconnections have become a necessity for extremely dense logic circuits.[1] Bottom-up assembly of metallic one-dimensional (1D) nanostructures is one of the most efficient methods to construct nanocircuits. Silver nanowires (Ag NW), one of the nanostructured materials, have attracted considerable interest because of their excellent electrical conductivity and mechanical properties. Although some methods such as soldering,[2–4] voltage and/or current excitation,[5–8] thermal sintering,[9, 10] electron beam irradiation,[11–13] laser irradiation,[14, 15] and plasmon interactions [16] have been successfully used to create nanojunctions, local heating of some form is a general feature of these nanoscale welding techniques. As the size range transitions to the nanoscale, an increasing surface to volume ratio [17] in the nanostructured materials enhances their sensitivity to heat. However, local heating is often detrimental to the properties of the base material or damage the underlying substructures. In addition it is difficult to precisely control the application of heat at the nanoscale. Due to these limitations, the joining of Ag NWs without heating is essential to engineer nanocircuits and would be considered an attractive technical solution for the electronic industry. Lu et al.[1] have demonstrated that the cold welding of nanowires is possible by simply contacting two gold nanowires, such that surface-atom diffusion and orientedattachment leads to successful welding. In the case of Ag NWs with highly oriented crystal structure produced by synthesis from …
