“…Such plasma bombarding will greatly enhance the diffusing tendency of Ag atoms on AgNWs [22]. Similar conversion of AgNWs have also been found in AgNWs networks by laser-driven and electro-temperature driven Rayleigh instability at a temperature above 360 °C [23,24]. Obviously, the temperature needed for RF plasma treatment is much lower.…”

Highly ordered Ag particle-chains (AgPCs) have been obtained from Ag nanowires (AgNWs) by radio frequency (RF) plasma treatment. Such conversion is attributed to the fast nonequilibrium diffusion of Ag atoms (liquid-like behavior) on AgNWs surfaces through the plasma bombarding. Further, the formed AgPCs highly coincide with the predictions by Rayleigh instability. In contrast to heat treatment, AgPCs are formed rapidly, highly ordered and at temperature below 100 • C. Furthermore, aperiodicity and wire-wire welding instead of highly ordered particle-chains has been observed as the AgNWs are overlapped by plasma treatment. This work should provide a new perspective for metallic particle-chains fabrication.

“…The transmittance spectra of AgNW TCCs are presented in Figure 3b. All TCCs showed characteristic absorption peaks in the UV-region (300-350 nm), associated with AgNW surface plasmon resonance absorption bands [43,44]. The transmittance of TCC at 550 nm before irradiation was 80%, which after the irradiation changed only slightly across the entire visible range.…”

In this report, an improvement of the electrical performance and stability of a silver nanowire (AgNW) transparent conductive coating (TCC) is presented. The TCC stability against oxidation is achieved by coating the AgNWs with a polyvinyl alcohol (PVA) layer. As a result, a UV/ozone treatment has not affected the morphology of the AgNWs network and the PVA protection layer, unlike non-passivated TCC, which showed severe degradation. The irradiation with an intense pulsed ion beam (IPIB) of 200 ns duration and a current density of 30 A/cm2 is used to increase the conductivity of the AgNWs network without degradation of the temperature-resistant PVA coating and decrease in the TCC transparency. Simulations have shown that, although the sample temperature reaches high values, the ultra-high heating and cooling rates, together with local annealing, enable the delicate thermal processing. The developed coatings and irradiation strategies are used to prepare and enhance the performance of AgNW-based transparent heaters. A single irradiation pulse increases the operating temperature of the transparent heater from 92 to 160 °C at a technologically relevant voltage of 12 V. The proposed technique shows a great promise in super-fast, low-temperature annealing of devices with temperature-sensitive components.

Selective engineering of the interface between nanoscale components and the electrical properties of heterojunctions is key to the development of next-generation nanoscale circuit elements. In this paper, we show how laser processing of a metal-P type semiconductor nanoscale heterojunction between Ag and CuO nanowires can be used to control the nature of the electrical contact by reducing the Schottky barrier at the Ag-CuO interface to Ohmic contact. Elimination of the Schottky barriers occurs in response to lattice matching of Ag( 111)∥CuO(111) planes at the interface induced by controlled irradiation with femtosecond (fs) laser pulses. An interdiffusion region with a mixed Ag/CuO composition is also present over a localized area of the interface between the Ag and CuO nanowires after fs laser processing, but both Ag and CuO nanowires remain crystalline away from the heterojunction. In addition, the Ag nanowire becomes totally embedded in the larger CuO nanowire after irradiation. Fabricated nanowire devices from Ag-CuO nanowire heterojunctions transition from a double-Schottky contact configuration prior to laser processing to a rectifying behavior as irradiation time increases. This study illustrates that fs laser processing can be highly effective in the engineering of electrical performance in metal-semiconductor nanoscale heterojunction devices.
