Significant THz absorption in CH₃NH₂ molecular defect-incorporated organic-inorganic hybrid perovskite thin film

The valid strong THz absorption at 1.58 THz was probed in the organic-inorganic hybrid perovskite thin film, CH₃NH₃PbI₃, fabricated by sequential vacuum evaporation method. In usual solution-based methods such as...
