在这个观点中，我们提出了二维（2D）材料中的极化子模式可以用来增加和控制纳米尺度上的光-物质相互作用。我们分析了支持等离激子、激子和声子极化子模式的最常用二维材料纳米结构的光学响应。利用极化子特征长度评价了不同二维材料单层和纳米带的光-物质混合模式。我们提出二维材料纳米盘可以像一个支持局域极化子模式的腔一样，可以被附近放置的量子系统激发，以呈现超快和超亮的运行。实现高质量二维极化模的关键是减少材料损耗。因此，引入了最先进的二维材料剥离、化学气相沉积和转移技术来制造纳米结构，以满足光子学、光电子学和量子技术应用的严格要求。(C) 2021作者。除另有说明外，所有文章内容均遵循知识共享署名（CC BY）许可协议（http://creativecommons.org/licenses/by/4.0/）。
In this Perspective, we present that polariton modes hosted in two-dimensional (2D) materials can be used to increase and control light-matter interactions at the nanoscale. We analyze the optical response of the most used 2D material nanostructures that support plasmon, exciton, and phonon polariton modes. Polariton characteristic lengths are used to assess the hybrid light-matter modes of different 2D material monolayers and nanoribbons. We present that the 2D material nanodisk can act like a cavity that supports localized polariton modes, which can be excited by a nearby placed quantum system to present ultra-fast and ultra-bright operation. The key to achieve high quality 2D polariton modes is to reduce material losses. Thus, state-of-the-art exfoliation, chemical vapor deposition, and transferring techniques of 2D materials are introduced to fabricate nanostructures that fulfill the stringent requirements of applications in photonics, optoelectronics, and quantum technologies.
