Abstract

In this work, we experimentally investigated the terahertz optical modulation properties of the quartz-based lead perovskite halide (MAPbI3) thin film. The MAPbI3 thin film were fabricated on quartz substrate by the traditional solution spin coating method. Terahertz time-domain spectroscopy (THz-TDS) system was used to measure the terahertz wave transmission characteristics of the MAPbI3/SiO2 sample under the external optical pumping. The experimental results show that the terahertz transmittance of MAPbI₃/SiO₂ sample is obviously affected by the external optical pumping power, and the modulation depth of terahertz wave can reach more than 72.36%. The experimental study shows that the MAPbI3 thin film will be widely used in terahertz modulator, filter, photoelectric switch, photoelectric detector and so on. It has positive practical significance and good application prospect to carry out the application research of lead halide perovskite material in the field of terahertz technology.
