Tunable optical properties of nanoporous gold leaf metamaterials

Porous Gold Nanolayer Coated Halide Metal Perovskite-Based Broadband Metamaterial Absorber in the Visible and Near-IR Regime

“…8 illustrates. The motivation of this comes from the previously reported study that shows the use of a porous NAF would increase the absorptivity and add tunability to the structure [34]. Such NAF layer can be realized [24], [26] that determine the electrical properties of the same experimentally.…”
