摘要：
光子器件严重依赖于其制造所用的介电材料，较高的折射率和较低的吸收损耗能够带来新的功能和更高的性能。然而，这两个材料特性通过经验性的Moss规则内在关联，该规则指出，介电材料的折射率随着其带隙能量的增加而降低。超越该规则的材料，称为超Mossian介电材料，具有大的折射率和宽的光学透明性，因此是先进光子应用的理想候选者。本文综述了高折射率介电和半导体材料日益扩大的领域，特别关注那些超越Moss规则的材料。我们讨论了电子能带结构中带边附近较大的联合态密度如何导致超Mossian行为，以及第一性原理计算筛选如何加速其发现。最后，我们确立了折射率对纳米共振器、波导和超材料性能的限制作用，突显超Mossian介电材料作为光子技术下一步性能跃迁的有前景的途径。
英文摘要：
Photonic devices depend critically on the dielectric materials from which they are made, with higher refractive indices and lower absorption losses enabling new functionalities and higher performance. However, these two material properties are intrinsically linked through the empirical Moss rule, which states that the refractive index of a dielectric decreases as its band gap energy increases. Materials that surpass this rule, termed super-Mossian dielectrics, combine large refractive indices with wide optical transparency and are therefore ideal candidates for advanced photonic applications. This Review surveys the expanding landscape of high-index dielectric and semiconductor materials, with a particular focus on those that surpass the Moss rule. We discuss how electronic band structures with a large joint density of states near the band edge give rise to super-Mossian behavior and how first-principles computational screening can accelerate their discovery. Finally, we establish how the refractive index sets the performance limits of nanoresonators, waveguides, and metasurfaces, highlighting super-Mossian dielectrics as a promising route toward the next performance leap in photonic technologies.
