Simultaneous Improvement in the Corrosion Resistance and Visible Transparency of ZnO/Cu/ZnO Transparent Heaters with Reactively Sputtered Al2O3 Layers

In this study, we report a methodology that simultaneously improved the corrosion resistance and visible transparency of ZnO/Cu/ZnO transparent heaters with addition reactively sputtered Al2O3 layers. To assess resistance, ZnO layers thicknesses in range 0-20 nm were deposited onto 20 nm-thick Cu layer, behavior underlying was investigated by evaluating sheet change an 85 °C/85% humidity test. While layer not effective moisture barrier, showing increase more than 50% after 10,000 m, below 5 did show observable for equal duration. Optical transmittance also constructing glass/ZnO/Cu/ZnO/Al2O3 structures varying top layers, 10-30 10-60 nm, respectively The bottom fixed at 30 10 nm. results revealed average light ZnO/Cu/ZnO/Al2O3 structure increased 2.5% over optimized structure.
