AI总结:

本研究展示了ReS2晶体中腔模式与激发态的强耦合形成里德伯极化激元,澄清了其光谱特征源于高折射率与大振子强度的结合,为固态里德伯系统提供了新平台。

摘要:

二硫化铼(ReS2)属于第VII族过渡金属二硫属化物(TMDs),具有吸引人的特性,如极高的折射率和显著的振子强度、大的面内双折射以及良好的化学稳定性。与大多数其他TMDs不同,ReS2的奇特光学性质从体相持续到单层,使该材料可能适用于光学器件应用。在这项工作中,我们以前所未有的清晰度展示了腔模式与激发态之间的强耦合,这导致了强烈的极化激元相互作用,显示出此类材料作为里德伯原子系统的固态对应物的价值。此外,我们明确澄清了重要光谱特征的性质,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TMDs所表现出的极高折射率和大振子强度的有趣结合。

英文摘要:

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.
