论文摘要
我们通过浸入二氯甲烷（DCM）和乙醇的混合溶液中，证明了单层WS2中有序耦合的实时激子操作。通过调整混合比率，可以实现从178 MeV（In乙醇）到266 MeV（在DCM）的连续调整。结果主要归因于单层WS2中中性激子比例的显着增加（从59％到100％），因为DCM的浓度增加。它为进一步研究分层材料中的有序耦合以及量子信息处理和非线性光学材料的潜在应用提供了一项重要的垫脚石。
We demonstrate the real-time exciton-manipulation of plexcitonic coupling in monolayer WS2 coupled to a plasmonic nanocavity by immersing into a mixed solution of dichloromethane (DCM) and ethanol. By adjusting the mixture ratio, a continuous tuning of the Rabi splitting energy ranged from 178 meV (in ethanol) to 266 meV (in DCM) is achieved. The results are mainly attributed to the remarkable increase of the proportion of neutral exciton in the monolayer WS2 (from 59% to 100%) as the concentration of DCM is increased. It offers an important stepping stone towards a further study of plexcitonic coupling in layered materials, along with potential applications in quantum information processing and nonlinear optical materials.
