In this work, we report an amplified strong coupling phenomenon in a hybridized nanowire. The hybridized nanowire structure is composed of CH₃NH₃PbBr₃ perovskite nanowire coated by SiO₂ film and silver film. Due to the existence of silver film, Rabi splitting in hybrid structure can reach 303.2 meV, while the Rabi splitting in a pure perovskite nanowire is only 236.4 meV. Also, thicknesses of SiO₂ film and Ag film can control the Rabi splitting of hybridized structure: (i) the thicker the Ag film, the greater the Rabi splitting; (ii) the thinner the SiO₂ film, the greater the Rabi splitting. Finally, index of SiO₂ film shows a linear relation with Rabi splitting.

金属膜包覆钙钛矿纳米线模拟系统中强耦合的放大

在这项工作中，我们报告了杂化纳米线中放大的强耦合现象。杂化纳米线结构由外覆SiO ₂膜和银膜的CH ₃ NH ₃ PbBr _{3钙钛矿纳米线组成。}由于银膜的存在，混合结构的拉比分裂可以达到303.2 meV，而纯钙钛矿纳米线的拉比分裂只有236.4 meV。此外，SiO ₂膜和Ag膜的厚度可以控制杂化结构的Rabi分裂：（i）Ag膜越厚，Rabi分裂越大；(ii)SiO ₂膜越薄，拉比分裂越大。最后，SiO _2的指数影片显示了与拉比分裂的线性关系。
