摘要

．我们回顾了允许调谐单层半导体的吸收和发射特性的物理机制。我们使用过渡金属二硫化物单层模型系统，如MoSe 2或WSe 2，因为它们非常有效的光-物质相互作用和高质量样品的可用性。对于包裹在六方氮化硼中的单层，激子光学跃迁线宽的均匀和非均匀贡献都可以调整，从而开辟了调整范德华异质结构的反射率和吸收的途径

Tuning absorption and emission in monolayer semiconductors: a brief survey

. We review the physical mechanisms that allow tuning of absorption and emission characteristics in monolayer semiconductors. We use the model system of transition metal dichalcogenide mono-layers such as MoSe 2 or WSe 2 due to their very e ﬃ cient light-matter interaction and availability of high quality samples. For monolayers encapsulated in hexagonal boron nitride both homogeneous and inhomogenous contributions to the exciton optical transition linewidth can be tuned opening up pathways for tailoring the reﬂectivity and absorption in van der Waals heterostructures

期刊介绍： The Comptes Rendus - Physique are an open acess and peer-reviewed electronic scientific journal publishing original research article. It is one of seven journals published by the Académie des sciences. Its objective is to enable researchers to quickly share their work with the international scientific community. The Comptes Rendus - Physique also publish journal articles, thematic issues and articles on the history of the Académie des sciences and its current scientific activity. From 2020 onwards, the journal''s policy is based on a diamond open access model: no fees are charged to authors to publish or to readers to access articles. Thus, articles are accessible immediately, free of charge and permanently after publication. The Comptes Rendus - Physique (8 issues per year) cover all fields of physics and astrophysics and propose dossiers. Thanks to this formula, readers of physics and astrophysics will find, in each issue, the presentation of a subject in particularly rapid development. The authors are chosen from among the most active researchers in the field and each file is coordinated by a guest editor, ensuring that the most recent and significant results are taken into account. In order to preserve the historical purpose of the Comptes Rendus, these issues also leave room for the usual notes and clarifications. The articles are written mainly in English.
