Fig. 1: Rabi splitting and optical characterization of MoS2.
From: Quantifying photoinduced carriers transport in exciton–polariton coupling of MoS2 monolayers
a Exciton–polariton coupling system between a plasmonic cavity with a resonant ωp and TMD excitons. In this system, the parameters that determine the coupling strength are the energy-exchange rate Ω, cavity loss rate γ, and emitter loss rate κ. The right panel depicts the energy diagram of the strong coupling of the 2D TMD semiconductor with a direct bandgap ћωbg between the ground state |g〉 and excited state |e〉 coupled to the plasmonic-cavity mode ћωp. The coherent coupling forms a hybrid state with UPB and LPB separated by Rabi splitting energy ћωR. b The Raman spectra of the MoS2 monolayers after being transferred on the Au film. The frequency difference between the \(E_{{\mathrm{2g}}}^1\) and A1g modes is 19.81 cm–1, which indicates monolayers. c PL spectra of the MoS2 monolayers.
