“…This value is quite close to that of bulk silver (15.9 nΩ.m), and is consistent with values previously measured by Huang et al for single crystal Ag nanowires. 36 No dependence of the resistivity on nanowire diameter was observed for the nanowires measured -see Supporting Information for more information. This resistivity value was then used to estimate R1 and R2, and to extract values for Rjxn.…”

Networks of silver nanowires appear set to replace expensive indium tin oxide as the transparent conducting electrode material in next generation devices. The success of this approach depends on optimising the material conductivity, which up to now has largely focused on minimising the junction resistance between wires. However, there have been no detailed reports on what the junction resistance is, nor is there a known benchmark for the minimum attainable sheet resistance of an optimised network. In this paper we present junction resistance measurements of individual silver nanowire junctions, producing for the first time a distribution of junction resistance values, and conclusively demonstrating that the junction contribution to the overall resistance can be reduced beyond that of the wires themselves through standard processing techniques.

Composite made of multiwalled carbon nanotubes coated with silver was fabricated by an electroless deposition process. The thickness of silver layer is about 40 to 60 nm, characterized as nano-crystalline with (111) crystal orientation along the nanotube's axial direction. The characterization of silver/carbon nanotube [Ag/CNT] nanowire has shown the large current carrying capability, and the electric conductivity is similar to the pure silver nanowires that Ag/CNT would be promising as building blocks for integrated circuits.PACS: 81.05.uj, carbon nanotubes, carbon-based materials, diamond/nanocarbon composites.

“…In a publication by Huang et al 18 it was shown that the electrical resistivity of a single crystalline trapezoidal AgNW is dominated by the electron diffusely scattering on the nanowire surface and explained their experimental results using Chamber's approach 19 to the Fuchs and Sondheimer theory. 20,21 Their work was focused to differentiate the sur- face scattering from the grain boundary scattering and for single crystal wires the experimental resistivity fits well to the theoretical resistivity models that are close to purely diffuse surface scattering.…”

Silver nanowire arrays embedded inside polycarbonate templates are investigated as a viable thermal interface material for electronic cooling applications. The composite shows an average thermal diffusivity value of 1.89×10−5 m2 s−1, which resulted in an intrinsic thermal conductivity of 30.3 W m−1 K−1. The nanowires’ protrusion from the film surface enables it to conform to the surface roughness to make a better thermal contact. This resulted in a 61% reduction in thermal impedance when compared with blank polymer. An ∼30 nm Au film on the top of the composite was found to act as a heat spreader, reducing the thermal impedance further by 35%. A contact impedance model was employed to compare the contact impedance of aligned silver nanowire-polymer composites with that of aligned carbon nanotubes, which showed that the Young’s modulus of the composite is the defining factor in the overall thermal impedance of these composites.
