Designed and experimentally achieved 1D layered W-HfO2 metamaterial emitter structure. (a) Schematic presentation of the designed emitter structure. (b) STEM image shows the cross-sectional view of the as-fabricated 1D emitter structure. The Al2O3 substrate is not shown in the schematic and STEM image.
