“…[66] Ag-based core-shell nanowires fabricated by sol-gel is another promising way to achieve transparent electrodes with enhanced stability. [67,68] In spite of many experimental efforts devoted to the stability improvement of AgNW-based TCMs, a deep understanding of the main mechanisms leading to network failure is still missing. As experimentally observed, the degradation of the AgNW networks usually initiates with a local defect that subsequently propagates over a larger area.…”

Silver nanowire (AgNW) networks are among the most promising indium-free, flexible transparent electrodes for energy, lighting and heating devices. However, the lack of stability of such networks is a key factor that limits their industrial application. While applications require homogeneous networks, non-homogeneous AgNW networks are intentionally prepared in the present work to probe the mechanisms leading to failure under electrical stress. We show that induced non-homogeneities have a strong impact both on the spatial distribution of temperature (measured by IR imaging) and the current density throughout the electrode (as deduced from modeling). Regions with higher current density under elevated electrical stress are correlated to the origin of degradation. Furthermore, the influence of a zinc oxide (ZnO) layer on electrical performances of non-homogeneous specimens is studied. Thanks to ZnO coating, the tortuosity of electrical potential lines measured by the one-probe mapping technique is much lower than for bare networks. Additionally, coated network electrical failure occurs at 40 % higher voltage compared to bare network, over 18 V, while reaching superior power-induced heating of 360 °C. The results presented here will contribute to the design and fabrication of more robust nanowire networks, particularly for application in transparent heaters.

“…Among them, Au NWs are the most expensive and Cu NWs have a great potential to oxidize, which reduces the stability and conductivity of the film. − Thus, we chose Ag as the raw material for TCEs. At the same time, Ag NWs have a wide range of applications, including flexible transparent conductors, touch panel, electronics, and energy devices. − However, random metal geometries represent a trade-off between optical transmittance and conductive properties. Thinner and sparser layers provide better optical transmission but reduce the electrical conduction and vice versa.…”

The transparent conductive electrodes (TCEs) composed of silver nanowires (Ag NWs) have shown promising applications recently. In this study, we propose a solution-assembled process to obtain the pattern controllable and uniform-ordered Ag NW grid TCEs by combining with the lithographic technique. The transmittance of Ag NW grid TCEs is controlled by the pattern of grids, but its sheet resistance can be tuned by the diameter of Ag NWs in the grids. As the pattern of grids is fixed, conductive property will improve with the decline of the diameter of Ag NWs. This is a new and efficient strategy to resolve the trade-off between optical transmittance and conductive properties of the random metal nanowire networks for optoelectronic devices.

“…Various types of surfactants are also frequently used to assist and control the anisotropic growth of the atomic Ag nanoparticles to Ag nanowires that include hexadecyl-trimethylammonium bromide (CTAB) [51][52][53], sodium dodecyl sulfonate [54][55][56], vitamin B 2 [57][58][59], polyvinyl acetate (PVA) [60,61], dextran [62] and polymethyl vinyl ether [63]. In most chemical approaches, the employed charged precursor contains ions of the desired metal [64].…”

The recent interest to nanotechnology aims not only at device miniaturisation, but also at understanding the effects of quantised structure in materials of reduced dimensions, which exhibit different properties from their bulk counterparts. In particular, quantised metal nanowires made of silver, gold or copper have attracted much attention owing to their unique intrinsic and extrinsic length-dependent mechanical properties. Here we review the current state of art and developments in these nanowires from synthesis to mechanical properties, which make them leading contenders for next-generation nanoelectromechanical systems. We also present theories of interatomic interaction in metallic nanowires, as well as challenges in their synthesis and simulation.
