摘要:

二维(2D)材料是一个迷人的光子平台,具有小器件规模、快速运行速度以及低能耗,这要归功于它们的面内晶体结构和面外量子限制。该研究领域进一步发展的关键是能够修改2D材料的光学特性。这些改变通常来自材料本身,例如改变其化学成分。本文通过对光子环境的工程设计,综述了一种探索较少但很有前途的方法。而不是修改材料本身,这意味着操纵电介质和金属环境,均匀和纳米结构,直接与材料相互作用。对于只有一个或几个原子厚的2D材料,与环境的相互作用可以非常有效。本文综述了这种相互作用的三个自由度:弱耦合,强耦合和多功能性。此外,它回顾了一个相对定时的工程概念,直接应用到二维材料的图案化。受益于纳米光子学的蓬勃发展,光子环境工程提供了一种多功能和创造性的方法来重塑2D材料中的光-物质相互作用。

英文摘要:

A fascinating photonic platform with a small device scale, fast operating speed, as well as low energy consumption is two-dimensional (2D) materials, thanks to their in-plane crystalline structures and out-of-plane quantum confinement. The key to further advancement in this research field is the ability to modify the optical properties of the 2D materials. The modifications typically come from the materials themselves, for example, altering their chemical compositions. This article reviews a comparably less explored but promising means, through engineering the photonic surroundings. Rather than modifying materials themselves, this means manipulates the dielectric and metallic environments, both uniform and nanostructured, that directly interact with the materials. For 2D materials that are only one or a few atoms thick, the interaction with the environment can be remarkably efficient. This review summarizes the three degrees of freedom of this interaction: weak coupling, strong coupling, and multi-functionality. Also, it reviews a relatively timing concept of engineering that directly applied to the 2D materials by patterning. Benefiting from the burgeoning development of nanophotonics, the engineering of photonic environments provides a versatile and creative methodology of reshaping light-matter interaction in 2D materials.
