Layered materials are very attractive for studies of light–matter interactions at the nanoscale. In particular, isolated quantum systems such as color centers and quantum dots embedded in these materials are gaining interest due to their potential use in a variety of quantum technologies and nanophotonics. Here, we review the field of nonclassical light emission from van der Waals crystals and atomically thin two-dimensional materials. We focus on transition metal dichalcogenides and hexagonal boron nitride and discuss the fabrication and properties of quantum emitters in these systems and proof-of-concept experiments that provide a foundation for their integration in on-chip nanophotonic circuits. These experiments include tuning of the emission wavelength, electrical excitation, and coupling of the emitters to waveguides, dielectric cavities, and plasmonic resonators. Finally, we discuss current challenges in the field and provide an outlook to further stimulate scientific discussion.

原子薄材料中的单光子源

层状材料对于纳米级光-物质相互作用的研究非常有吸引力。尤其是,孤立的量子系统,例如嵌入在这些材料中的色心和量子点,由于它们在各种量子技术和纳米光子学中的潜在用途而受到关注。在这里,我们回顾了范德华晶体和原子薄的二维材料的非经典发光领域。我们将重点放在过渡金属二硫化碳和六方氮化硼上,并讨论这些系统中量子发射器的制造和性能以及概念验证实验,这些实验为它们在片上纳米光子电路中的集成提供了基础。这些实验包括调整发射波长,电激发以及将发射器耦合到波导,介电腔,和等离子共振器。最后,我们讨论了该领域当前的挑战,并提供了一个前景,以进一步激发科学讨论。
