Temperature-tunability of perovskite quasi-bound states in the continuum-metastructure for enhanced terahertz performance and CO2 sensing

MAPbI₃ characteristics

The complex refractive index of MAPbI₃ is calculated using Eqs. (1–5) in the supplementary information and is depicted in Fig. 3. Since we use x- and y-polarized light to investigate the optical response of the…
