论文摘要
Rhenium二硫化物（RES2）属于VII型过渡金属二甲藻元化（TMDS），具有吸引人的特性，例如异常高的折射率和显着的振荡力强度，大型的平面外向性外向性和良好的化学稳定性。与大多数其他TMD不同，RES2的特殊光学性质从批量延伸到单层，使得这种材料可能适合于光学设备中的应用。在这项工作中，我们以前所未有的清晰度证明了腔模式和激发态之间的强耦合，这导致了巨大的偏光量相互作用，这表明了诸如rydberg原子系统的固态对应物等材料的兴趣。此外，我们明确地阐明了重要的光谱特征的性质，阐明了一些有争议的方面或不完整的解释，并证明它们的起源是由于这些TMD表达的非常高的折射率和较大的振荡力的有趣组合所致。
Rhenium disulfide (ReS2) belongs to group-VII transition metal dichalcogenide (TMDs) with attractive properties such as exceptionally high refractive index and significant oscillator strength, large in-plane birefringence, and good chemical stability. Unlike most other TMDs, the peculiar optical properties of ReS2 persist from bulk to the monolayer, making this material potentially suitable for applications in optical devices. In this work, we demonstrate with unprecedented clarity the strong coupling between cavity modes and excited states, which results in a strong polariton interaction, showing the interest of such materials as a solid-state counterpart of Rydberg atomic systems. Moreover, we definitively clarify the nature of important spectral features, shedding light on some controversial aspects or incomplete interpretations and demonstrating that their origin is due to the interesting combination of the very high refractive index and the large oscillator strength expressed by these TMDs.
