Artificial metamaterials with hyperbolic dispersions exhibit unusual optical properties not found in Nature. Such hyperbolic metamaterials (HMMs) permit the access to and control of electromagnetic waves with large wave vectors. An important criterion for multilayer-based HMMs is whether the thickness of each individual layer can be far below the operating wavelength while still maintaining the material and interfacial quality. Herein, we report heteroepitaxial growth of HMMs composed of multilayers of ultrathin indium tin oxide (ITO) and indium oxide (In₂O₃) films. The disparate metallic and dielectric properties of the individual building blocks, in conjunction with the good carrier mobility and film morphology enable a low-loss infrared HMM platform on which we demonstrate ultrafast optical switching and the enhancement of the radiative decay rate of PbS quantum dots in the telecommunication wavelength regime.

具有外延ITO-In ₂ O ₃多层的低损耗近红外双曲超材料

具有双曲分散性的人工超材料表现出自然界中未发现的异常光学特性。这种双曲线超材料（HMM）允许使用大波矢访问和控制电磁波。基于多层的HMM的重要标准是，每层的厚度是否可以远低于工作波长，同时仍保持材料和界面质量。本文中，我们报道了由超薄氧化铟锡（ITO）和氧化铟（In ₂ O ₃）电影。各个构建基块的不同金属和介电特性，以及良好的载流子迁移率和薄膜形态，共同构成了低损耗的红外HMM平台，在该平台上，我们证明了超快的光学开关和PbS量子点的辐射衰减率的增强。电信波长范围。
