▲ [18p-221B-2] [INVITED] Terahertz Longitudinal Modes in Organic-Inorganic Hybrid Perovskites

〇Masaya Nagai1 (1.Osaka Univ.)

Keywords:THz spectroscopy, LO phonon, organic-inorganic hybrid lead halide perovskites

We performed THz time-domain spectroscopy for of organic-inorganic hybrid lead halide perovskites, which constitute a promising materials system for solution-processed high-efficiency solar cells. We evaluated the energy loss function, representing the longitudinal excitation, and showed that it is critical for the optoelectronic properties.
