ZnO/Ag/ZnO nanolaminate structures were deposited by consecutive RF sputtering at room temperature.The optical transparency, sheet resistance, and figure of merit are determined in relation to the deposition time of Ag and to the film thickness of the ZnO top layer. An improved transmittance has been found in the visible spectral range of the ZnO/Ag/ZnO structure compared to ZnO multilayers without Ag. High transmittance of 98% at 550 nm, sheet resistance of 8 Ω/sq, and figure of merit (FOM) of 111.01 × 10−3 Ω−1are achieved for an optimized ZnO/Ag/ZnO nanolaminate structure. It is suggested that the good optical and electrical properties are due to the deposition of the discontinuous Ag layer. The electrical metallic type conductivity is caused by planar located silver metal granules. The deposition of a discrete layer of Ag nano-granules is confirmed by atomic force microscopy (AFM) and cross-section high-resolution transmission electron microscopy (HRTEM) observations.

“…Low-E films are generally deposited using a continuous sputtering system, 10) and the top and bottom MO layers are responsible for maintaining the low resistivity of the Ag layer, which has the most important effect on performance. 11) The MO layers further serve to adjust the visible light transmittance 12,13) and to protect the Ag layer when the glass is machined or thermally processed. 14,15) It has been reported that Ag layers with preferential (111) orientation in the plane parallel to the substrate have lower resistivity.…”

Silver-based low-emissivity films have been studied to improve window insulation performance. We have reduced the resistivity of Ag in glass/ZnO/Ag structures by inserting a TiO2 in the lowermost layer. In another study, we have also found that the resistivity of Ag thin film can be reduced by changing the sputtering gas from Ar to Kr. In this study, both methods were adapted to achieve even lower resistivity and the factors involved were analyzed in detail. The lowest electrical resistivity achieved was 3.4 μΩ·cm for a combination of a glass/TiO2/ZnO/Ag structure and Kr gas sputtering, which was 22% less than that for a glass/ZnO/Ag structure with Ar gas sputtering. X-ray diffraction, atomic force microscopy, and secondary ion mass spectroscopy results indicated that the important factor influencing the electrical resistivity was a reduction in the amount of sputtering gas trapped in the Ag layer by depositing the layer using Kr gas.

“…3) However, the ITO film is known to suffer from a thermal stability issue and comprised of the rare and expensive indium element. 4) Therefore, an alternative novel transparent conducting coating must be developed to replace or reduce the use of ITO. 5) Under such a circumstance, the TCO=metal=TCO-based multilayer structure has been extensively investigated as one of the most promising candidates that can be used to replace ITO.…”

Transparent conductive oxides (TCOs) have been widely used in various optoelectronic devices. Among these TCOs, indium–tin oxide (ITO) is the most commonly used TCO material. However, owing to the scarcity of indium, there exists a strong need to replace ITO with an alternative transparent conductive coating. A TCO/metal/TCO-based multilayer structure has been considered as one promising candidate. In this work, several Al-doped ZnO (AZO) AZO/Ag/AZO samples were prepared with different Ag thicknesses. The AZO/Ag/AZO structure allows a low sheet resistance of around 10 Ω/sq and a visible transmission above 80% achieved with an overall thickness of ∼110 nm. The optimisation of front AZO thickness helps to reduce reflection via destructive interferences. We demonstrated that the adhesion strength of the stacks can be improved by modifying top AZO deposition conditions. The adhesive tape test confirms good film adhesion (i.e., peel-off strength) to the glass substrate. The annealing studies confirm good thermal stabilities of the fabricated sandwich structure.
