Abstract

AbstractNanolaminates built from ultra‐thin, ultra‐smooth films of amorphous metals, and solution‐processed oxides represent a new platform for dispersion engineering. Materials exhibiting anisotropic elliptical dispersion and hyperbolic dispersion with positive refraction are realized through choice of amorphous metal and laminate design. Transmission electron microscopy (TEM), X‐ray photoelectron spectroscopy (XPS), polarized reflectance measurements, and effective medium theory are combined to demonstrate the precision and predictability of the fabrication techniques and optical properties from ultra‐violet to infra‐red frequencies.magnified image Engineering anisotropic dielectric response through amorphous laminate structures.
