Ultrathin Silver (Ag) films (~3-20 nm) have potential applications in, optical devices, solar devices, sensors, electronics and plasmonic devices. It shows plasmonic resonance, and have good optical transparency, electrical and thermal conductivity, and mechanical flexibility. However, the growth of continuous ultrathin Ag thin film on a ceramic substrate cannot be achieved. This has been attributed to the low affinity of Ag towards ceramics substrates (Volmer–Weber growth), which also results in poor adhesion. Some approaches are used to stabilize ultrathin Ag films on ceramics. Reportedly, they are seed layer and co-deposition techniques by using modifier materials like, Niobium, Germanium, Chromium, Nickel, Copper, Titanium and Aluminium. The reason for selecting the reported modifier layer is attributed to their higher oxygen affinity than Ag. If relative oxygen affinity is the only reason, then Zn should also work as a modifier material. We used Zn as modifier layer and confirm that under a very specific sequence of deposition an stable ultrathin Ag film that is transparent and conducting is achieved. Ag films with a thickness 15 nm are deposited by DC magnetron sputtering after deposition of few nanometres of Zn metal on glass, quartz, and silicon substrates. 8 nm Ag films deposited on 2nm Zn modifier layer have mean absolute surface roughness of ~1.5 nm and shows sheet resistance of ~ 3 Ω/Sq, and have transparency of ~ 65 % to visible light. Based the comparative sheet resistance of the ultrathin Ag films, we propose an atomic structure of the substrate, Zn and Ag heterostructure. Zinc partially or fully fills the nano roughness associated with the substrates and forms atomically chemically graded interface with Ag. Thus, leading to smoothly varying chemistry across the substrate and Ag, which we refer as 3-D interface. We will confirm the proposed structure using APT. The ability of Zn to fill the substrate roughness partially or fully could result in improved adhesion of Zn along with the Ag to the substrate, which would be confirmed. Effect of Ag ultrathin patterning as nanoribbons on its plasmonic resonance will be studies.
