Abstract
In this study, we fabricated transparent heaters composed of an ultrathin Cu-layer heating element sandwiched between a ZnO underlayer and an Al₂O₃ overlayer. With the Cu layer thickness fixed at 8.5 nm, the thicknesses of the ZnO and Al₂O₃ layers were independently varied to reach the optimum antireflecting condition (maximum..... More

Abstract
In this study, ultrathin (4-40 nm) Cu-layer-based transparent heaters prepared on glass substrates were investigated for cost-effective applications. The Cu heaters were embedded between ZnO layers serving as anti-reflection and anti-corrosion layers. The Cu layer thicknesses varied in the range of 4-40 nm, and the corresponding structural, electrical, optical and..... More

Abstract
In this study, we report a methodology that simultaneously improved the corrosion resistance and visible transparency of ZnO/Cu/ZnO transparent heaters with the addition of reactively sputtered Al₂O₃ layers. To assess corrosion resistance, ZnO and Al₂O₃ layers with thicknesses in the range of 0-20 nm were deposited onto 20 nm-thick Cu..... More
