Keywords:LO phonon, THz spectroscopy, methylammonium lead halide perovskite single crystal

We performed THz time-domain spectroscopy for methylammonium lead halide perovskite single crystals to characterize LO phonon. We also measured the spectra of the luminescence to discuss carrier-phonon interaction.
