Author(s): Masaya Nagai, Takuya Tomioka, Masaaki Ashida, Mizuki Hoyano, Ryo Akashi, Yasuhiro Yamada, Tomoko Aharen, and Yoshihiko Kanemitsu We performed terahertz time-domain spectroscopy for methylammonium (MA) lead halide perovskite single crystals and characterized the longitudinal optical (LO) phonons directly. We found that the effective LO phonon wave number does not change in the wide temperature range between 10 and 300 K. Howev... [Phys. Rev. Lett. 121, 145506] Published Fri Oct 05, 2018
