Electron-phonon coupling in an optically accessible, terahertz-tuneable cavity

Caption

a, Schematic representation of the coupling of material and field states producing hybrid light-matter polariton states P⁺ and P⁻. We explore here whether the formation of phonon-polaritons can modify electron-phonon interactions. b Sketch of a perovskite thin film in an optically transparent Fabry–Pérot cavity, with a tunable cavity length of ~100’s of µm, so that its fundamental mode resonates at THz frequencies.
